Hygger 1200W Submersible Aquarium Heater for 160-300 Gallons

This external temperature controller for a fish tank heater features a large LCD digital screen that intuitively displays the current water temperature, real-time power, and allows you to preset the target temperature. You can easily adjust the temperature from 59°F to 93°F, and a red indicator will show the heating state.

Our aquarium water heater comes with a built-in water sensor system that efficiently detects when the water level drops below the surface at the top of the heating unit. In such an event, the heater will automatically shut off and emit an alarm to let you know about the abnormal state. When the power is restored, the memory function will recall the temperature you had previously set, eliminating the need to reset it and avoiding temperature shocks.

The 400-watt aquarium heater is equipped with a double sensing probe that can detect overheating. If the water temperature exceeds the measurable range, the safety alarm function will be triggered, and the heater will automatically shut off the power, displaying an 'HH' code alarm when temperatures exceed 95°F. Conversely, if the temperatures drop below 59°F, an 'LL' code alarm will be displayed, and the heater will automatically turn on to heat up to the preset temperature.

This submersible aquarium heater utilizes dual-tube quartz glass material and high-temperature-resistant nickel-chromium heating wire to provide more consistent and efficient heating. The ABS guard shield has an irregular hollowed-out design, which helps to better diffuse the heated water and prevent your aquatic pets from being burned.

The product specifications are as follows: ① Dimensions: 11.6"x 2.7"x 1.2" ② Power: 1200W, suitable for 160 to 300-gallon aquariums ③ Power Cord: 6.2ft + 3.9ft ④ Voltage: AC100-240V ⑤ Temperature control range: 59°F~93°F (temperature deviation of ±1°F)

The heater comes with two powerful suction cups that make it easy to firmly attach to the side of the tank. Please ensure the heater element is fully submerged in water, at least 2 inches underwater, and that the top of the unit is facing upwards so that the probe can accurately sense the water level.
