Eheim Jager TruTemp Aquarium Heater

EHEIM JÄGER Precision Aquarium Heaters
Made in Germany

Many fish from tropical and subtropical regions do not feel comfortable at room temperatures that are comfortable for us humans.  That is why precisely regulated, constant water temperature is very important for your aquarium inhabitants.

Before the engineer Eugen Jäger invented the adjustable aquarium heater, there wasn’t any really satisfactory solution for controlling the water temperature suitable for different species.   Everyone resorted to complicated and sometimes odd methods.  Some put the aquarium in the sun or next to the radiator/heater.

Obvious ideas are often the best ones!  For example, the invention of the aquarium heater as a rod.  The heating rod is simply hung in the water and it heats the water!  It is true that the principle is still the same as decades ago, but a lot has changed.  Today, the JÄGER adjustable heater is an ultra-modern electronic thermal device produced with the best available technology.  Its new jacket of laboratory glass offers real benefits over the competition.  Here are some excellent selling points:

•The temperature can be precisely adjusted from 18° to 34°C and recalibrated if required. The control accuracy is +/- 0.5° C.

•The heat is kept at a constant level.  The heating function is indicated by a control lamp.

•The heater can be fully immersed, and is protected against dry running and is suitable for fresh or marine water.

•The glass jacket enlarges the heating surface and ensures optimum even-heat emission.

•Laboratory quality glass jacket.  This glass was developed for research purposes, therefore, it is free from pollutants that could be released into the water.  It is resistant to chemical and biological substances.  It does not have any fissures and hair cracks through which condensation water could penetrate.  And even extreme fluctuations of temperature that can occur when the water is changed does not bother this glass.

All Heaters include 1 Dual Suction Cup Heater Holder.  You may purchase replacement heater holders below if needed.
