Dual Display Digital Aquarium Heaters by Aquatop


The D2HT Digital Heater Series features a highly visible dual temperature display, an easy-to-use temperature control button, and a separately attached temperature sensor to provide a stable temperature environment for your aquatic life.

Too much temperature fluctuation can be very harmful to your aquarium ecosystem. The D2HT Dual Display Heater eater is easy to set your target temperature. When the water drops below the desired temperature, the heater will heat and maintain the warm water needed. When it reaches your target, it shuts off.

Just set it and go. The separate temperature sensor (located away from the heater for accurate readings) communicates with the heater to tell it to turn on or off depending on the current temperature of the water and the target temperature you have set. Internal memory insures that in the event of a power outage, the heater will resume your preset temperature settings once power is restored.
