JBJ True Temp Digital Controller w/ Heater - 300 Watt


JBJ introduces the TRUE TEMP digital heater controller and titanium heating system. The TRUE TEMP is the most complete heating system to date with the most advanced features that set it apart as the leading heater for professional hobbyists.

Our digital microprocessor boasts amazing +/- 0.5 F accuracy, a calibration setting, indestructible titanium heating element with thermal shut off, smart memory chip, LED heating indicator, safety guard, remote temperature probe, and a large constant LED display of the current temperature.

Maintaining the correct temperature for tropical fish may be the single most important factor for a successful aquarium. Since fish do not have the ability to regulate their own body temperature, it is crucial that we can provide consistent water temperatures with minimal fluctuations.

Majority of fish cannot cope with stress from constant temperature fluctuations, which leads to a compromised immune system. This increases the probability of avoidable diseases, parasites, and bacterial infections.

Most heaters have an integrated temperature probe within the same heating element. This can lead to false readings and premature ON/OFF cycles. The TRUE TEMP digital controller is equipped with a remote quick disconnect temperature probe that can be placed up to 5 feet away from the heating element for a comprehensive temperature measurement of the total volume of water. Quick disconnect temperature probe grants easy replacement without the need to replace the entire controller in the event it fails.

All titanium heating elements are securely placed inside our safety guards that protect you and your livestock from the heating core. Our flow thru design grants continuous water contact without interruption.

Have you ever noticed that majority of heaters cannot be calibrated. Often times, errors do occur during the calibration process. The ability to cross reference ensures your temperature is accurate and always correct.

An integrated smart memory chip will restore the previous temperature set point and calibration to the last stored setting once the power returns after a failure. This alleviates having to manually reset settings forever.
