Hygger 100W Aquarium Heater with LED Digital Display Thermostat Controller

Product Description: Rapid Heat Accumulation

The heating rod is made of explosion-proof quartz glass material and a high-temperature resistant nickel-chromium heating wire with silicon carbide heat conduction, making the water heating faster and safer, more durable, and longer-lasting.

LED Digital Temperature Display

The flashing LED digital display allows you to press the button to adjust preset temperatures and access more functions for flagging low/high temperature and out-of-water warning signs. The external controller makes operation easy and safe to use. Each touch changes the set temperature by 1°F (1°C), and you can press for 5 seconds to switch between Celsius and Fahrenheit.

01 Safety Mask

The high-temperature protective cover made of high-quality ABS material can prevent pet fish from directly touching the heating element during swimming.

02 Strong Suction Cup

Dual suction cup holders plus a spare suction cup hold the heating rod securely in place. Install the heating rods underwater as needed.

03 Rotate 90 Degrees to Install the Suction Cup

04 Safety Plug: Explosion-Proof and Anti-Corrosion Aquarium Heater

The heating rod heating body is made of explosion-proof quartz glass, nickel-chromium heating wire, and silicon carbide heat-conducting material, while the fish heater shield is made of high-temperature resistant ABS material. It is manufactured into a tank heater that is anti-corrosion, non-leakage, non-conductive, explosion-proof, and makes water heating faster.

Safety Guarantee

This full immersion aquarium heater has two temperature probes. When the fish heater is out of water or over temperature, it will automatically stop heating and send out a warning signal L1 or HH. The heating rod will restart after it is completely submerged in water or cooled.

Intelligent Thermostat

When the actual temperature is lower than the set temperature of the fish tank heater by 1.5°F/1.5°C, the indicator light will turn red, the fish tank heater will heat up to the set temperature at full power, and the indicator light will turn blue, then stop heating. The temperature range is from 59°F to 93°F.

External Smart HD Controller

The external controller with LED digital display allows you to adjust the temperature without getting your hands wet. Each press of the submersible heater will change the set temperature by 1°F (1°C). Press and hold it for 5 seconds to toggle between Celsius and Fahrenheit.

Full Submersible Heater

The 100W aquarium heater is suitable for 5-26 Gal fish tanks, both freshwater and saltwater. It has a memory function that remembers the temperature you set it to when the power fails. The three suction cup brackets can stably fix the heater in every corner of the fish tank.
