EHEIM JÄGER TruTemp Precision Heaters for aquariums.

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 German 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.

The invention of the aquarium heater as a rod was one of the best “obvious” ideas.  Simply hang in the water to heat and while the principle is still the same as decades ago, 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 temp can be adjusted from 18 to 34 C and recalibrated if needed. The control accuracy is +/- 0.5 C. The heat is kept at a constant level and 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.  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 it will not bother this glass.

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