Hygger Water Quality Meter

Hygger Water Quality Meter is used to accurately measure and monitor water quality parameters such as TDS, EC, pH, salinity, and temperature in various environments like drinking water, swimming pools, freshwater aquariums, and hydroponics.

Why You’ll Love It
Featuring a large LCD, auto-calibration with included pH buffers, and ATC (Automatic Temperature Compensation), this hygger meter ensures reliable and precise water measurements, providing accurate readings of TDS, EC, pH, salinity, and temperature. It is compact, portable, and ideal for maintaining a healthy aquatic environment with minimal effort.

Key Features
Complete 5-in-1 Testing
Instantly measures TDS, EC, pH, salinity, and temperature to monitor water quality with precision. The one-button lock reading function helps lock reading even if the TDS Meter is taken out of the sample. Turn on the switch, put the probe into the water, stir (make the small glass ball fully contact the liquid), and the value can be read.

Reliable & Quick Readings
Built to provide consistent results with ATC, a waterproof sensor, and battery-powered convenience. The water meter is equipped with 4 high-sensitivity probes, which can measure PH, TDS, EC, SALT, and TEMP. with high precision at the same time. Shows real-time readings for all parameters simultaneously, with easy-to-read values.

Memory Function
Retains settings between measurements for convenience.

Measurement Ranges & Accuracy
TDS: 0–9999 ppm, 1 ppm resolution, ±2% accuracy;
EC: 0–9999 μS/cm, 1 μS/cm resolution, ±2% accuracy;
pH: 0–00, 0.01 resolution, ±0.05 pH accuracy;
Salinity: 0–9999 ppm;
Temperature: 0.1–60°C / 32–140°F, ATC included.

Widely Application
This hygger 239 pH/TDS meter can help you find out the quality of water. It can be used to test drinking water, swimming pools, pond and freshwater aquariums, pH balance, RO system, SPA, or hydroponics.
Basically, all the environments that need to test the pH value can use this WATER tester to get an accurate value. Lightweight design (95±8g) makes it convenient for home or professional use.

Easy Automatic Calibration
Comes with three pH buffer powders (4.00, 6.86, 9.18) for effortless calibration.
Equipped with Automatic Temperature Compensation (ATC) that ensures accurate measurements across a wide range of temperatures (0.1-60°C/32.1-140°F). You can calibrate effortlessly to ensure the accuracy of the measurements. TDS EC is calibrated before leaving the factory and can be used out of the box.

Usage Tips
Calibration: Use the included pH buffers for auto-calibration. Immerse the electrode in the solution, press and hold the “CAL” button, and wait for the LED to flash 3 times to confirm calibration.
Measurement: Immerse the probe in water (without exceeding the max level), wait for readings to stabilize, and press “HOLD” to lock the value.
Before use: Soak the probe in water for two minutes to activate the probe before use or calibration.
After Use: Rinse the probe with distilled water, dry, and replace the cap.
Battery Replacement: Replace the 4×5V LR44 batteries when the display dims or readings become inconsistent.
Safe Placement: Keep the meter’s control buttons and battery compartment away from water; only the probe is water-resistant.
Regular Checks: Test water frequently to ensure stable aquarium conditions and optimal plant or fish health.

Thought Provoking
Format: Kindle
I bought this book after I heard the author on a podcast. Growing up in the US we have been inundated with the story that the collapse of the Soviet Union was an inevitable triumph of liberal, Western values. I had my doubts. Even poorly run dictatorships can muddle along for years. What the author did was center Gorbachev in the story. He was the eye of the storm. It was the terrible combination of Gorbachev’s ambitious idealism and gross ineptitude that led to the dismantling of the Soviet Union. Unlike much of Marxist historical narratives which emphasize the forces of history; the author shows that it’s individuals who shape events and are shaped by them. A different person than Gorbachev could have turned the tide in a different direction and left us a different world than we have today. This is a history book that teaches lessons not just about the Soviet Union but about human history in general.

A compelling account of the fall of the USSR
Format: Kindle
Zubok describes blow by blow the series of decisions that sent the USSR towards disaster. Gorbachev, widely hated in Russia, comes across as principled but indecisive, ignorant of economics, and incapable of translating his worship of Lenin into coherent action. The book reads like a thriller despite the density of facts. Zubok is a pessimist, but his thesis is convincing.

Fascinating, an against the grain account of the perestroika era
Format: Kindle
Gorbachev is hailed as a hero in the West but the book tells the story of a meek, naive individual that precipitated the fall of the Soviet Union creating suffering and an a!most unprecedented calamity.

A masterfully falsified history of the late Soviet developments
Format: Paperback
This book represents academic propaganda, providing some interesting insights into important events. Some details are true, but some crucial details are omitted. It represents a sanitized version of Russia's modern history. It provides misleading information about Gorbachev's constitutional reforms, aimed at partitioning of 15 republics into 53 confederation entities. Originally, the targeted republics were Kazakhstan, Moldova, Georgia, Azerbaijan, Ukraine, etc. Those conflicts were manufactured by the Soviet center to discredit "nationalists," facilitate the partition of national republics, and grant Moscow right to protect ethnic minorities. According to Starovoitova, Bakatin, Yakovlev, and a few other primary sources, the Soviet security services led special operations in the Caucasus and Central Asia to provoke those conflicts. Zubok avoids citing those parts. Using the imperial approach of "divide and rule," Moscow attempted to become a peacekeeper in the conflicts it created between different ethnicity. In addition to fragmenting the republics with well-developed national identities, Gorbachev's new constitution would revoke their right to leave the USSR, written in Lenin's 1922 Constitution (Shakhnazarov, 1992). Zubok does not explain any of it. His book is an effort to protect the truth and conceal facts with Russian myths and lies about nationalism (also referred to as Nazism). Notably, Zubok does not recognize non-Russian republics and describes them as "territories." He mentions Pitsunda as a resort on the Black Sea, not as Georgia. For lying about the genocidal ethnic cleansing conducted by the Russian military against the Georgian population of Abkhazia, Zubok owes apology to the victims of conflicts and wars initiated by Gorbachev and carried on by Yeltsin. The story about "the hardliners coup against Gorbachev" is also a big fat lie. American scholars, Amy Knight, John Dunlop, and William Odom provide more accurate insights. For Russian sources, read Marshal Shaposhnikov or Aleksandr Lebed's memoirs (1995) and listen to Gennady Yanaev's interview (2009). According to Mitrokhin archives (original), the August 1991 coup was an active measure the KGB developed per Gorbachev's request. The so-called coup was part of Gorbachev's constitutional reform, which would lead to the removal of unfriendly leaders (including Yeltsin) from the republics. It failed because the Soviet military brass, foremost Pavel Grachev, had defected to Yeltsin earlier in 1991. When you read a book by a seasoned Russian propagandist, like Zubok or Trenin, take it with a grain of salt, because it will always contain a mix of lies and truth.

An important work and worth the time.
Format: Hardcover
Real scholarship addressing difficult but important topics in history, economic history, and development. What every economist should read to think much more deeply about how institutions, culture, and human agency interact. At the same time, scholars like the three co-authors demonstrate that there still remains the possibility of doing work that isn’t larded with ideological or activist posturing. Highly recommended.
