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.

My dachshund loves this bone
My dog absolutely loved this bone!! He has other bones but always resorts back to this one. It’s easy for him to hold and enjoy at the same time. It is very durable.

Dogs give the Y a 10 out of 10!
It seems like all dogs love these Y bones. It is not messy and its a dog favorite. Paid for many Y bones in the store but it is a little more going to a pet store. So tried online. Didn't disappoint! Cant have enough in my pantry. 😀

My Dog Loves It, But Be Careful
My dog absolutely loves the Benebone Wishbone Chew Toy—he gets so excited every time I bring it out. It’s clearly made for aggressive chewers and is very durable, but he often ends up hurting his teeth while chewing on it. I wish it were a bit gentler on his mouth. Great for keeping dogs entertained, just watch out if your pup has sensitive teeth.

My dogs LOVE these over the leading brand!
My dogs LOVE these chew bones! They will chew on these things for 30 minutes straight. They will dig them out from the dog basket, or whine at the door if they left it outside. I ended up having to get all 4 of my dogs each their own it was so popular. The white bone in the picture is the from the leading brand and you can see which one they go for, lol. They've had these bones for 6 weeks now and chew on them daily, and multiple times throughout the day. If your dog is a chewed or puppy, definitely give these a try!

It'll only last a week
Size: 5 Inch, Color: Classic Bone, Size: 5 Inch, Color: Classic Bone
We've only had it a few days and she's already half way through it. It won't last the week. She doesn't eat it, she spits out the pieces. If you buy it was a consumable, totally worth the money. I'll probably buy my power chewer a couple a month
