hygger 500W 800W Aquarium Heater, Submersible Fish Tank Water Heater with External Color LED Digital Temperature…

????LED DIGITAL DISPLAY CONTROLLER: ① Shows real-time water temperature or set temperature, three-digit show, water temperature show correct to 0.1 °F, simple to learn. ② 4 varieties of labor directions – Working/Malfunction/ Thermostatic/ Out of water, simple to know. ③ Improve the buttons to extend the sense of contact, and the operation is straightforward and simple, simply cycle the buttons.
????RAPID HEATING: Quickest 5 seconds warming, the inner materials is up to date and upgraded, utilizing titanium metal materials, which is safer to make use of, not simple to deform, and has very sturdy corrosion resistance. Robotically reduces energy when approaching the set temperature, totally makes use of thermal power inertia to easily attain the set temperature, saving power.
????INTELLIGENT THERMOSTAT: Over-temperature safety prevents “cooking fish”. When the water temp exceeds about 93.5 °F, begin alternately flashing EE fault code; and over 97℉, the heater will cease heating mechanically. When the water temp cool all the way down to 93℉, the heater will begin working mechanically. As well as, it has a power-off reminiscence operate and no must set it once more.
????ANTI-DRY PROTECTION: When the heating rod is uncovered to air, show ER fault code and the heater will shut off mechanically. When the heating rod is totally immersed in water, it’ll begin working mechanically. Successfully lengthen the service life.
????HIGH-QUALITY MATERIALS: Constructed-in twin temperature probe, real-time monitoring of water temperature, temperature accuracy of ± 1 °F; excessive temperature resistant ABS materials, no deformation and no softening, explosion-proof and anti-corrosion, no leakage of electrical energy. Sturdy suction cup bracket, can stably repair the heater in each nook of the fish tank.
