hygger Aquarium Heater,75W/150W/300W Submersible Fish Tank Water Heater Double Quartz Explosion-Proof with for Freshwater Saltwater Tank

DIGITAL DISPLAY & EXTERNAL CONTROLLER: Easy to use, LED digital display, external hand controller, press 1 time adds 1 degree, can be set between 59℉(15℃)~93℉(34℃), easy to know the real-time temperature. The working status can also be displayed, red light on: heating, green light on: constant tempe ANTI-DRY PROTECTION: Intelligent temp sensing, when the heater is exposed to air, display ER fault code and the heater will shut off automatically. When the heater is completely immersed in water, it will start working automatically. Effectively extend the service life. It has a power-off memory function and no need to set it again OVER TEMPERATURE PROTECTION: Intelligent induction device, stable work, good performance, over-temperature protection, avoid cooking fish due to high temperature. When temp pass 95 °F, the LED display showsflashing 95 number code, red and green light flash together, the heater will shut off automatically SAFE AND ANTI-BURN: The nickel-chromium heating wire materials has higher thermal energy efficiency, and then conducts heat through silicon carbide material, which effectively utilizes electrical energy to convert into thermal energy, with long service life and uniform heating, with quartz glass material, safe explosion-proof and anti-burn. The exterior high tempe resistant plastic cover, not easy to deform SMALL NOT TAKE UP SPACE: hygger 75W/150W heater can be installed horizontally or vertically, also for saltwater & freshwater, and can be used in various small turtle and fish tanks, which can fully meet your needs. Note: Do not put the heater in the sand.Please make sure that the water surface is at least 2 inches above the heater Fully submersible: The heater is fully submersible. Please note, The heater should be fully submerged to work properly Rapid thermal 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; which result in faster water heating and a safer, more durable, long-lasting heater. Build-in intelligent LED digital temperature display: LED digital display screen shows the current and preset water temperature. The external hand controller makes for easy setting and operation. Every press changes the set temperature by 1℉. The led flashes 5 seconds and then stops, indicating that the temperature has been set and the display shows the current temperature.
