Hygger 1200W Submersible Aquarium Heater for 160-300 Gallons

External Temperature Controller
Intuitive LCD Digital Display
This hanging fish tank heater features a large, user-friendly LCD digital screen. The screen intuitively displays the current water temperature and real-time power status. You can preset the target temperature with ease. The range for setting the temperature is from 59℉ to 93℉, and a red indicator lights up to show the heating status.

Safety Features
Advanced Safety Mechanisms
Our aquarium water heater includes an efficient built-in water sensor system that accurately detects water level and warns you in case it falls below the top of the heating unit. When an abnormal state is detected, the heater automatically shuts off and emits a beep alarm. The memory function will automatically restore to the set temperature when power is restored, eliminating temperature shocks and the need to reset.

Over-Temperature Protection
Enhanced Safety with Aging Sensing Probes
Equipped with a 1200 watt submersible aquarium heater, this temperature controller has dual sensing probes. If water temperature exceeds the measurable range (above 95℉ or below 59℉), the safety alarm function is triggered. The system automatically shuts down the power and displays an 'HH' code alarm for overheating or an 'LL' code for temperatures below the minimum, auto-heating back to the preset temperature.

Intelligent Heating System
Consistent Heat Delivery
This submersible aquarium heater utilizes dual tube quartz glass material and high-temperature resistant nickel-chromium heating wire for consistent and efficient heating. The ABS guard shield, with its irregular hollowed-out design, facilitates better diffusion of heated water, ensuring even temperature distribution. This also prevents your aquatic pets from being burned.

Product Parameters
Dimensions & Specifications
The external temperature controller has dimensions of 11.6''x2.7''x1.2''. It is designed for aquariums ranging from 160 to 300 gallons and has a power cord of 6.2 ft + 3.9 ft. The voltage is AC 100-240V, and the temperature control range is 59℉~93℉ (temperature deviation of 1℉). It comes with two powerful suction cups that ensure the heater firmly adheres to the side of the tank. Place the heater element at least 2 inches underwater with the top of the unit facing upwards to ensure accurate temperature sensing.
