Hygger 200W Aquarium Heater for 20-52 Gallon Freshwater and Saltwater Tanks with LED Thermostat

Product Description

Rapid Heat Accumulation: Crafted from explosion-proof quartz glass, the heating rod features a high-temperature resistant nickel-chromium heating wire and silicon carbide material for efficient heat conduction. This combination not only accelerates the water heating process but also enhances safety, durability, and the longevity of the heating element.

LED Digital Temperature Display: The integrated LED digital screen, which flashes to indicate settings, allows you to easily adjust preset temperatures at the press of a button. This user-friendly feature includes alerts for low/high temperatures and warnings for out-of-water situations. The external controller ensures safe and straightforward operation. Each press alters the temperature by 1°F (1°C), and holding down the button for five seconds enables switching between Celsius and Fahrenheit.

Safety Mask: To protect your pet fish, a high-temperature protective cover made from premium ABS material prevents direct contact with the heating element while they swim.

Strong Suction Cups: Dual suction cup holders, along with an extra suction cup, secure the heating rod firmly in position. You can conveniently install the heating rods underwater as required. For optimal installation, remember to rotate the suction cup 90 degrees.

Safety Plug: This aquarium heater, featuring an explosion-proof and anti-corrosion design, boasts a heating body constructed from explosion-proof quartz glass, nickel-chromium heating wire, and silicon carbide. The protective shield is made from high-temperature resistant ABS material, ensuring that the heater is non-corrosive, leak-proof, non-conductive, and explosion-proof, all while promoting efficient water heating.

Safety Guarantee: Designed with two built-in temperature probes, this fully submersible aquarium heater safeguards against overheating or operating without water. Should these critical conditions occur, the heater will automatically cease functioning and emit warning signals (L1 for low water and HH for high temperature). It will reactivate once entirely submerged in water or after it cools down adequately.

Intelligent Thermostat: The heater features a sophisticated thermostat mechanism. When the actual temperature drops below the set temperature by 1.5°F/1.5°C, the indicator light will illuminate in red, signaling the heater to activate at full power. When the desired temperature is reached, the light turns blue, indicating that the heater has halted operation. The temperature can be set anywhere between 59℉ and 93℉.

External Smart HD Controller: This heater is equipped with an external controller, complete with an LED digital display that keeps your hands dry during adjustments. Simple pressing will adjust the set temperature by 1℉ (1℃). To switch between Celsius and Fahrenheit, hold the button for five seconds.

Full Submersible Heater: Rated at 200 watts, this aquarium heater is appropriate for use in 20-52 gallon freshwater and saltwater tanks. It features a memory function that recalls your set temperature in the event of a power outage. Additionally, with three suction cup brackets, you can easily secure the heater in any corner of your fish tank.
