Feature: 1. Intelligent Chip, Fast Heat Conduction: Aquarium heater adopts Al intelligent chip, PID computer control system, intelligent frequency conversion, automatic constant temperature; titanium alloy stable heat conduction, fast heat up, energy saving and power saving. 2. Sensitive Detection, HD Display: Aquarium heater has a mini body, ultra thin diving, suitable for a variety of fish tanks. Dual temperature sensor, sensitive detection, abnormal temperature safety. HD display, heating failure at a glance. 3. Off Water Power Off Function: Aquariumheater heater has built in off water power off function, when the heating rod leaves the water surface, the LED screen will show L1, and keep flashing to remind, and the heating rod stops heating. 4. Over Temperature Protection System: Aquarium heater has built in over temperature protection system, when the water temperature exceeds 34℃, the screen will show HH and flash to remind and stop heating at the same time, when the water temperature is lower than 15℃, it will prompt LL and low temperature alarm. 5. LED Real Time Display: Fish Tank heater with LED display set temperature and real time water temperature, with high accuracy insulation head. When the heating rod working state, the red light is on, stop heating constant temperature state, the blue light is on. 6. Easy to Operate, Caution: Fish tank heater uses outside tank control, one key cycle, easy to operate. When changing water, please unplug the power switch first to avoid the residual temperature of the heater will damage the shell. 7. Intelligent Thermostat Mode: The heater starts an instantaneous burst of heat, rapid heating to the specified temperature, after reaching the specified temperature to intelligent thermostat mode, energy saving and power saving. Specification: Item Type: Aquarium Heating Rod Material: ABS Use: Fish Tank Heating Rod Power: 300W Temperature Control Range: 15-34℃ Applicable Water Volume: 90L. Package List: 1 x Aquarium Heating Rods2 x Suction Cups Note: 1. Use the heating rod completely submerged in water, to prevent burning the rod body, melting the protective shell and other situations cause unnecessary trouble.2. Because the heating rod heating speed is fast, try to place the heating rod in the position of rapid water flow to let the fish tank evenly heated.3. It is not recommended to put the heating rod in the bottom filter, because some bottom filter water level is not enough to submerge the rod body, and lead to accidents.4. Please do not bury the heating rod in the bottom of the fish tank gravel mud, because the gravel and water have different specific heat capacity, which will lead to damage to the heating rod.5. Heating rod will work with a slight static electricity (12V or less) is safe, please rest assured that the use.
