Hygger Aquarium Heater,600W/800W Submersible Fish Tank Water Heater Double Quartz Explosion-Proof With Separate Temperature Measurement System For Freshwater Saltwater Tank (600W)

hygger Aquarium Heater can fully convert electric energy into heat energy, saving energy and safety. Two-digit digital display, easy to grasp the temperature value. Over-temperature protection system, when the temperature in the tank is over 93 °F will stop heating, to avoid fish from boiling fish due to high temperature. Heater temperature ranges from 59℉(15℃) to a max of 93℉(34℃). After the water evaporates, the heater is exposed to the water surface, it will automatically cut off the electricity. Fully submersible: Please note, the heater should be fully submerged in water to work properly.
