🔥【Explosion-proof Quartz Glass Aquarium Heater Durable and Safer】The heater made of explosion-proof quartz glass material and a high-temperature resistant nickel-chromium heating wire with silicon carbide heat conduction,faster water heating and long lasting.2 hours heating 1℃.The shell is a high temperature resistant PC material, which can effectively protect the fish from scalding. 🔥【Temperatures Ranges 59℉ to 93℉,Automatic Heating】The heating rod built-in thermometer,When the water temperature is lower than the set temperature by 1℉, the heater will automatically heat up, and stop heating when the water temperature is consistent with the set temperature.Fahrenheit and Celsius can be converted to each other,Pressing and holding for 5 seconds changes temperature display from Celsius to Fahrenheit. 🔥【LED External Controller with Indicator Light】The controller is not waterproof, please keep away from water，LED digital display screen shows the current water temperature and preset temperature.The number above the controller is the current water temperature, and the number below is the set temperature,Red light means heating,Blue lights indicate constant temperature,blue light flashing indicates the heater not fully submersibled.

🐠 Digtal Display & External Controller: Easy to use, LED digital display, adjustable external temperature, can be set between 68℉~94℉, easy to know the real-time temperature. The working status can also be displayed, Red light on: Heating, Blue light on: Constant Temperature. PS: Press one time adds one degree.Long press for three seconds to switch between Celsius (℃) and Fahrenheit(℉). 🐠 Fast Heating Speed & Energy Saving: Under the same conditions, the heating speed is 2-3 times that of the ordinary heating rod, and it can save 50% of electricity for you.
