🐠【Explosion-proof Ceramic Aquarium Heater】The heating element of the 50W Aquarium Heater is composed of the explosion-proof quartz glass tubes and high-temperature resistant ceramic heating core, using the latest submarine technology for fast, consistent, and more evenly distributed heat. Housed in of V0 grade ABS flame retardant plastic for IP68 waterproof, corrosion resistant, and high-temperature resistance makes the fish tank heater stronger.
🐟【Overheating & Out of Water Protection】When the aquarium heater head out of the water, the heater will automatically stop heating, the controller will display the “E1” until the heater is completely submerged in the water. If the water temperature exceeds 34°C/94°F, the heater will automatically stop heating, and the controller will display the “HH” until the water temperature drops below 34°C/94°F.
🐙【Precise Temperature Control System】M2 grade precision water sensor forms an accurate water temperature sensing system. Automatic Constant Temperature Function: Temperature accuracy is ±1°F, when water temperature is higher than the set temperature, the adjustable aquarium heater will automatically stop heating; when water temperature is lower than the set temperature, the adjustable fish tank heater will restart heating.
