Hygger 900W Submersible Aquarium Heater with Temp Control & Auto Off

External Temperature Controller

Intuitive Temperature Control: Discover precise and easy-to-use temperature control with our external fish tank heater. Featuring a large, readable LCD digital screen, this controller intuitively displays the current water temperature in real-time and allows you to preset and adjust the target temperature.

Adjustable Temperature Range: Easily adjust the water temperature to your desired settings from 59℉ to 93℉. A red indicator clearly shows the heating state, providing you with peace of mind.

Water Level Detection and Safety: Our heater includes an advanced water sensor system that efficiently detects low water levels at the top of the unit. Should the water level fall below this point, the system automatically shuts off and beeps an alarm. This ensures your heater operates safely and prevents potential damage.

Memory and Recovery Function:

Over-Temperature Protection: Equipped with dual sensing probes, our heater detects when water temperatures exceed 95℉ and triggers a safety alarm. The heater automatically shuts off and displays an 'HH' code alarm. Similarly, if temperatures drop below 59℉, the 'LL' code alarm and automatic heating ensure the water returns to your preset temperature.

Intelligent Heating System: Our submersible aquarium heater features dual tube quartz glass and high-temperature resistant nickel-chromium heating wire, providing consistent and efficient heat-up. An irregularly hollowed-out ABS guard shield ensures better diffusion of heated water and prevents scalding of your aquatic pets.
