Maintaining a consistently correct temperature is important to the health of your aquarium fish. Hagen pre-set, submersible aquarium heaters feature a thin, compact design that's easily hidden so it won't take away from the beauty of your aquarium.
These are the safest, most technologically advanced heaters available. A thin layer of thermosensitive carbon and organic resins allows for heat resistance that increases along with temperature, meaning that the unit cannot overheat; even if left out of the water. Thermostat remains accurately calibrated even if the knob is turned too far; and a digital temperature indicator allows accurate setting to within 1 degree Fahrenheit. For use in fresh and saltwater aquariums.
Illuminated top and side temperature readings. High thermal diffusion for efficient heating. 500-micron, solid silver contact thermostat prevents overheating. This heater is fully submersible and has a 6-foot cord.
The PC Plus heaters are designed as a precision-made instrument to maintain accurate aquarium temperatures. The automatic thermostat and moisture-proof construction provide long-term, trouble-free service.
