About This

• 【500W intelligent variable frequency fish tank heater】 This 500W fish tank heater is suitable for 52-80 gallon fish tanks, with intelligent temperature control frequency conversion, voltage 110-120V, temperature control range (68-93℉/17-34℃) Precise temperature control ±0.1℉, with PID controller, and is suitable for both fresh and sea water.
• 【Dry-burn protection and overheating protection】 When the heating rod system detects lack of water or overtemperature, the red and green lights on the heating rod will flash together and force heating to stop to protect the safety of fish and aquatic life.
• 【Intelligent frequency conversion and power saving】 Based on PDI optimization algorithm temperature control, it automatically reduces power when approaching the set temperature and maintains the water temperature at the lowest power to achieve energy saving.
• 【Explosion-proof quartz tube glass】 Made of nickel-chromium heating wire, safe and durable, good thermal conductivity, fast heating, corrosion-resistant and universal for freshwater and seawater, the shell is made of high-temperature resistant ABS material, which can effectively protect fish from scalding.
• 【Widely Used】500W adjustable aquarium heater is suitable for many occasions, such as fish tanks, aquariums and small fish ponds.
