Calibrating your Eheim Jager Heater

The reason Jager heaters have a reputation for being the most accurate heaters available is the ability to recalibrate the heater.

The factory setting should be reasonably close but if you moved either the red arrow or the blue dial before reading the instructions you may need to recalibrate the heater.

  • Features a shatterproof glass construction
  • TruTemp dial adjusts from 65° to 93° F
  • Thermo safety control enables 'running dry' protection
  • On/off indicator light verifies heater functions
  • Includes mounting bracket and suction cups
  • Simple and safe recalibration (±2 °C)
  • Generous 5.6 foot cord

Eheim Jager TruTemp Submersible Heater

300 Watts

Precisely regulated, constant water temperature is very important for the comfort and success of your aquarium inhabitants. The Jäger TruTemp adjustable heater is an ultra-modern electronic thermal device offering today's best technology. Designed for use in both freshwater and saltwater aquarium, Jäger TruTemp fully-submersible heaters include these great features:

Shatterproof glass construction - Made with laboratory-grade glass, TruTemp heaters are free of pollutants, resistant to chemical and biological substances, and able to withstand extreme temperature fluctuations. Their glass jackets also enlarge the heating surface and ensure even heat distribution.

TruTemp Dial - Temperature can be precisely adjusted from 18° to 34° C (65° to 93° F). Using the TruTemp dial with readjustment ring, the user can recalibrate the heater for a precise temperature reading. Control accuracy is +/- 0.5° C.

Thermo Safety Control - This safety mechanism enables 'running-dry' protection. The heater will shut off when removed from the water, and resume functioning upon return.

On/Off Indicator Light - This convenient feature eliminates guessing and enables the user to verify heater function without getting their hands wet!

Each Jäger TruTemp Heater also includes a mounting bracket and suction cups for secure and flexible placement within your aquarium system. Lastly, an extra long power cord accommodates most applications.

So Far So Good
I adopted a young adult dog less than 2 weeks ago. She had spent over 12 hours a day in a crate and has excessive energy and anxiety built up. She is a strong chewer. So far, out of 6 toys, this is the only one still in one piece. It appears sturdy and extra bouncy. So much better than regular tennis balls.

My dogs favorite!
My dogs love these! They will play all day if you'd let them, these balls are their favorites. I use the chuck-it handle and they get tons of exercise in the big yard!

The Dog LOVES IT!
I bought this for my ex-wife's Pitbull. He is an aggressive chewer and usually destroys any toy I buy him. But not this one! The ball is small enough and pliable that it gives when he chomps on it. He loves this ball and seems to be his favorite toy. Thank you for making a product that he likes and can't destroy!

My Golden Retriever’s favorite
We’ve owned lots of toys and balls. This specific version (in blue) has been her absolute favorite. She’s about 72lbs and chews on this thing regularly with no visible damage. We actually own about 6 of them because they have a tendency to go missing underneath furniture and in the yard. We have two of the orange colored ones but she doesn’t like those nearly as much which I assume is because the blue is easier to see in the grass. Other than that…They bounce really well and also whistle a little when you throw them hard enough. I hope they never stop making these.

doesn't whistle as loud as other chuckit balls I've seen, but a good ball.
makes some noise, but I've seen (and played with) others at the dog park that whistle much louder than the 1 I got. all Chuckit balls... so, just this one I'm betting. but it flys good and the dog loves to chase it. he chews it a fair bit as well and the ball has not taken much damage from him (lab mix) or others that have had a go at it. I'll likely buy another at some point ... just wish it was a little louder when flying.
