【500W Aquarium Heater】500W aquarium heater is suitable for 75 to 130 gallons of saltwater and freshwater aquariums. Voltage 110-120V, temperature control range 59-93℉ (15-34℃).
【Safety and Durable】The submersible aquarium heater is made of explosion-proof quartz glass material and high-temperature resistant nickel-chromium heating wire, with silicon carbide thermal conductivity, safer heating and longer service life. The sturdy black shell is high-temperature resistant ABS material to protect fish, aquatic life and you from burns.
【Multiple Protections】①Over-temperature protection, it will stop automatically when the set temperature is reached, and it will automatically power off and buzz an alarm when it exceeds 97.7℉. ②Power off when out of water, the heating rod will automatically power off when it leaves the water surface, and the side probe prevents dry burning and fire. ③APS anti-boiling fish system, APS automatically starts when the heating rod is out of control, and automatically cuts off the power within 10 seconds
