Proper usage of Solarmeter Ultraviolet Radiometer for Outdoor UV Index Measurement
The instrumentation used to measure UV index for the U.S. E.P.A./NWS program is directed toward the sky in a global normal (perpendicular to level ground) inclination. Therefore the Solarmeter Model 6.5 is designed to operate in the same fashion. Solar irradiance measured this way includes direct (reduced by cosine law depending on solar zenith angle) plus diffuse (diffused by the atmosphere).
This vertical (global) reading represents an average intensity value your body will experience while being active on a tennis or volleyball court, or lying flat on a blanket on the grass. If however, you are reclined in a lounge chair facing the sun perpendicular to the sun angle, you will experience a higher UV intensity, as represented by pointing the Solarmeter directly at the sun. This value will typically exceed the actual UV index number.
To obtain the UV index instantaneous value, the following instructions will provide the most consistent, accurate results:
- Stand clear of buildings, trees, etc. to obtain a "full sky" field of view.
- Hold the meter vertical out in front of your body.
- Press and hold button on front of meter case. Note reading on LCD. This value represents the instantaneous UV index.
- The highest UVI values typically occur when the sky is a deep blue color, and sometimes when the sun is between scattered white "puffy" clouds. Take extra precaution under these conditions to reduce sunburn potential.
Note that various cloud and haze conditions reduce the UV index. When partly cloudy, take readings often and average clear with cloudy readings to correlate with actual UV index. Take care in hazy or slightly overcast conditions because although the direct UV reads less than when sky is clear, the diffuse UV can be higher... as seen by pointing the meter in various directions.
Among the outdoor variables affecting UV intensity are:
- Seasonality/Sun Zenith Angle
- Location/Latitude/Geography
- Reflective Surroundings
- Altitude
- Weather conditions
- Ozone Layer Thickness
By regularly using the Solarmeter you will become very informed of damaging UV levels in many and varied conditions. This knowledge, along with following the outdoor precautions mentioned above, should help enable you to avoid sun damage.
Note: Battery operation voltage is 9V down to 6.5V. Below 6.5V the LCD numbers will begin to dim, indicating the need for battery replacement. Under typical service load, the battery should last about 2 years.

My Epson printer is total junk!
Color: White, Style: ET-2800-W, Pattern Name: Printer
I have had many printers over the years. I started with Canon dot matrix printers, and then ink jet printers. In the old days, and ink cartridge contained all the colors, so if red was out, you tossed away the rest of yellow and blue too. They were pricey and wasting ink wasn't something I was OK with. I would pull ink cartridges from dumpsters outside office supplies stores, take them home and draw the ink from them to fill my cartridges with. Then Epson came up with a cartridge for each color and black . That's when I switched to Epson and have used them ever since. I did have an HP in there when I got such a deal I couldn't pass it by, but after several years it died and I switched to Artisan printers. I still have an old 810 that is finicky and I don't want to have to coax it just to print a few pages. I got a WorkForce printer ,used it several times after I got it, and then it sat idle for 5 years or so. I moved recently and decided to set up the WorkForce printer. The new ink cartridges were practically new, but sat for 5 years maybe, so the nozzles and print head needed cleaning, I expected this. It uses mass amounts of ink to do this so then I was out of ink. I ordered new cartridges, and back to cleaning when they were inside. I never got anything to print, plus, the new paper I ordered was as glossy and slippery as photo paper, and the rollers couldn't grip it.
I gave up and ordered this printer as a replacement.
Setup went OK until I put paper in, then the rollers were slipping and I got jam messages, even though nothing was inside. I pulled the paper and let it finish the initial process. Then I put paper in when it wanted to align the print head. It fed paper OK for now, so I guess maybe I didn't get hosed on this Epson as I did buying the WorkForce Epson.

This is a frustrating printer!!!!
I'm using WIFI network to connect the printer to my laptop computer. I like to be able to print or scan from anywhere in the house. If you purchase this frustrating Epson printer, you now have a ball and chain around your leg. You can't print a simple document without some kind of error code popping up and requiring that go look at the minuscule little screen and try to figure out what button you must press to get the document printed. If I have to be right next to the printer, I might as well use a wired connection. I am disabled and it's a real inconvenience for me to have to go to the printer and squint at the tiny screen to try to figure out why it's been ten minutes of my time and I still haven't gotten my 1 page document in my hand. High speed printing is not high speed when you can't get a printed page without having to make several trips back and forth to the printer. I set the default paper to the standard plain white letter paper, only to find it wants to scan to photo paper, so it just sits there like a block of cement and nothing gets done. I had an Epson Artisan 810 that I really liked, except for the automatic feeder quit working so you had to stand there and feed each sheet to be scanned by hand. I didn't want a sheet feeder on the printer because they break down and the you're feeding by hand anyway. I just hate printing anything at all now because of this printer. I wasted several hours one day trying to print documents that I downloaded and needed a physical copy to present in person for a project I'm doing. Normally I would send a PDF file, and let someone else bother printing if that was necessary. After years of purchasing Epson printers, this is absolutely the last Epson I have spent my money on. Never ever again. The first clue should have been when the quick start guide suggested using a smart phone to set up the printer. I'm not going to work from my 5 x 7 phone screen when I can instead use a 15 inch laptop screen, and keyboard. It's simply a stupid idea. Sorry, but no more Epson for me ever!!!!
Update:

This is absolutely the most useless and frustrating Epson printer that I have ever ever owned. I cannot see good close up I need reading glasses to read. The digital screen on this printer is minuscule it's like a postage stamp size absolutely worthless. I have to carry a magnifying glass over to the f****** printer so that I can see what that little miniscule screen has to say on it. The most frustrating thing is every time I want to print something which is rare I don't print things every day the printer is not available is the message I always get I go over there by the printer I turn it off I turn it back on, that should clear out any crap that's on it so it's ready to print right? No you would be dead wrong! Instead you get a stupid little mini School screen and wants to be set on copy mode. I don't want to copy anything I don't want to scan anything I just want the damn thing ready to print. Anyway you come back to your your phone and you want to print and a printer still not available. I literally destroyed my phone I was that pissed off. I'm too old to be frustrated like that all the time. At 75 years of age I have had my share of printers over the years starting with the original dot matrix ones. Absolutely none of them were as difficult to use as this stupid printer I got now from Epson. When you want to print something you should be able to send it to the printer and it should print. You should not require a phone app to set the damn thing up! One thing I'll say, it's pretty good on ink because you can't make the damn thing print when you want it to !!!!!!!

Quality Printer
Color: Black, Style: ET-2800-B, Pattern Name: Printer
Wonderful multi purpose printer. I bought this months ago and finally got it set up. Set up was easy. Love that the printer is so light weight and fairly compact that I can move it wherever if needed. The supply of ink that came with it was awesome. The ink goes a long way. I have printed out a lot of photos on this printer and the quality has been very good. I have not encountered any paper jams. The photo printing has not been smudged nor has the color been uneven. From documents to photos this little printer does it all and does it very well. When my work printer dies I will be replacing it w another Epson Eco Tank for sure.

Printing is great, wifi is a problem (I figured out how to make it work!)
Color: White, Style: ET-2800-W, Pattern Name: Printer
I was on the fence about buying this printer because most of the 1 star reviews all said the same thing... "The Wifi would not work"
So I followed the instructions, Turned on the print, downloaded the IOS app, connected to the printer via Bluetooth, installed the ink, initialized the printheads. While that was going on, the app asked me to setup the wifi. a List of SSID's came up and I selected the one I wanted. I put in the password and it connected and the icon on the printer turned blue. I have a Unifi setup and I could see that the printer connected to access point #3 @ 2.4ghz and got an ip address. I locked the IP address to the printer.
(For my instructions to work for you, you need to make a reservation or lock the ipaddress that your DHCP server provided to the printer. ) If you don't do this, you will get a different address every time you turn the printer on and the computer and app will not be able to find the printer.
When the initialization was complete, the app on my phone said it could not connect to the printer. I decided to try to connect to a computer and come back to the phone app. I downloaded the software package from Epson and ran it. When it went to connect to the printer it could not find it and brings up a list of troubleshooting steps that are not likely to do anything.
There are videos about this problem and they are all useless. I am an IT professional with 26 years of experience. I am not going to unplug the printer and wait five minutes, I am not going to re-boot my router, I have a Unifi network environment with over 150 devices connected... (I have great wifi coverage, I am not moving my printer anywhere) My network works just fine, this printer is the issue!
So at this point, I know that the printer IS connected to my wifi and it got an IP address. This is not a wifi problem as everyone seems to think it is. It is an issue with the Epson software.
I decided to try to install it via the windows printer installer. I selected install via TCP/IP and put the ipaddress that my Unifi system provided to the printer. Windows found the printer and since the Epson app had already installed the drivers... just asked me what drivers I wanted to use. The ET-2800 showed up on the right hand side of the screen. I selected it, it installed and I was able to try a test print. It worked fine. I can print from my computer to the printer via the network.
Next was the phone app. The phone app has the option to find the printer via the IP address. I put the IP address in and it found the printer. The phone app works now too.
So, It took me some time to get this working, it should not have taken any time at all if the software worked correctly. The printer is really nice, it is a shame that the software is so bad when it comes to connecting to the printer.
So if you decide to buy one of these printers, save yourself the headache and just install using the ip address, it is quick and easy that way and it just works. I would have just purchased an HP printer, but I did not want to deal with all the issues of their subscription ink service. I feel like the cost of ink makes this printer worth the hassle of getting it to work.

Handles Photo-Quality Prints, Versatile Connectivity
Color: Black, Style: ET-2800-B, Pattern Name: Printer, Color: Black, Style: ET-2800-B, Pattern Name: Printer
I've had this printer for a whole year now. I was on a severe budget, looking for a photo-quality printer that didn't require Wifi in this digital age- because I quite frankly can't afford my own Wifi connection. My rink-a-dink laptop had to be set up with the software at my library, and an extra cord purchased.
All that said, I mostly print from my phone, because the software app is a bit easier to ensure that I get the highest quality setting. Laptop loves to be a snot about it. The blutooth feature, or "wifi direct", has a way about it, and as soon as you figure out what it wants, it gives minimal problems.
It functions exactly as if a printer had wifi on it, believe it or not.
What sold me on this model was the ability to do all of that, and adjust for different situations, seeing as other brands DEMAND constant wifi connectivity (lookin' at BROTHER, maybe Canon, too), and the long lasting ink tanks- I've printed hundreds of pages, and being a gothic/horror artist, at least a good part of the time, black is the only color even half gone.
What horrified me the most about printer-shoping dropping a lot of money (hundred plus is a lot over here, man) and not getting the prints to look like my work. Well, fear not. The attached pictures are why I made this review, to hopefully ease the anxiety of others. I make digital paintings, and use high DPI for high quality, and also the cutest micro-stickers you've ever seen. Prints come out clear, even if they can sit in the tip of my finger.
Yes, there are probably better printers. Maybe they're faster, and have even better connectivity, and have more bells and whistles. I specifically did not want to pay for those things, so, I'm very happy there's options.
It's not perfect, no, because every now and then, I get what I call a "special edition", where my printer has decided to multi-color barf out the last third of the page. One time it randomly printed in black and white. Well, that's no big deal, my stuff tends to look great in monochrome. Every now and then I get a low quality print; things just look a bit fuzzy. I'm not happy about that, but, you clean the heads, and print something simple and toony, and it has never done it twice in a row. Alignment has been off only one time, and I put the printer away after every session.
It occurs to me that people pay good amounts of money for printers that do that sort of thing anyway, so... Printers gonna printer, no matter where you try to hide.
Overall, I'm happy and relieved. I hope it lasts me a good long time. (Streetratt on Kofi, by the way.🖤 )

Amazing value and performance — perfect everyday home printer!
Color: Black, Style: ET-2800-B, Pattern Name: Printer
After lots of research and comparing ink costs, I finally purchased the Epson EcoTank ET-2800 Wireless Color All-in-One Cartridge-Free Supertank with Scan and Copy and it has been one of the best tech investments I’ve made for my home setup. Whether I’m printing documents, photos, homework, or creative projects, this printer delivers consistently reliable results without the usual stress over ink costs.
Right out of the box, setup was surprisingly easy. Epson’s app guided me through the wireless connection, and within minutes the printer was connected to my Wi-Fi and ready to go. The initial filling of the ink tanks took a few extra minutes, but the included bottles were clearly labeled and simple to use without mess.
The print quality has exceeded my expectations for an all-in-one home printer:
- Documents: Crisp, clean text — perfect for school assignments, work documents, letters, and recipes.
- Photos: Bright, colorful prints with decent detail (especially when using good-quality paper).
- Graphics & Crafts: I’ve printed worksheets, planner pages, labels, and even small art pieces — and everything looks sharp and vibrant.
- The speed is solid for its class. It’s not a professional office machine, but it doesn’t feel slow for everyday use.
Cartridge-Free Ink — Game Changer
This is the real highlight:
- Cartridge-free Supertank System:
Instead of tiny cartridges that run out in no time, this printer uses large refillable ink tanks — which means massive savings on ink long-term.
- Low Ink Cost:
You really feel the savings after your first few refills. I used to go through cartridges quickly, but now I only refill every few months — and even then, it’s affordable.
The included ink bottles provide a ton of pages, and you can easily track levels through the transparent tanks so you’re never caught off guard.
The wireless setup works smoothly. I can print from:
- My phone (via Epson app, AirPrint, or Google Cloud Print)
- My laptop or tablet
- Directly via Wi-Fi without cables
No more plugging USB in every time — super convenient.
The scanner is quick and easy to use:
- Scan photos
- Scan documents straight to email or phone
- Make copies without touching a computer
The scan quality is clear and accurate — ideal for digitizing receipts, forms, or school worksheets.
Pros:
- Huge savings on ink long-term
- Excellent print quality for text and color graphics
- Easy wireless setup and mobile printing
- Transparent tanks — see ink levels at a glance
- Scanner and copier work well for everyday tasks
- Quiet operation compared to older printers
Minor Notes
- Initial setup takes a bit longer because of ink filling — but it’s worth it.
- Photo prints are good for casual use, though super high-detail photography will still look better with dedicated photo printers or labs.
- No automatic document feeder (ADF) — so multi-page scanning requires manual pages.
The Epson EcoTank ET-2800 has transformed my printing experience. It’s affordable to run, produces great everyday prints, and the wireless features make it super convenient for the entire household. If you’re looking for a home printer that won’t drain your budget on ink, this one is absolutely worth it.
Whether you’re printing school documents, work files, planners, photos, or craft projects, this printer does it all with ease — and saves you money over time.
Highly recommended for home use — practical, efficient, and budget-friendly!
