Item Type: Aquarium Heater <br>Material: ABS <br>Use: Fish Tank Digital Display External Control Heating Rod <br>Plug Specification, Voltage: US Plug, 110V <br>Temperature Control Range: 15-34℃ <br>1、TITANIUM ALLOY HEATING MATERIAL: Submersible fish tank heater is made of titanium alloy heating material, fast heating speed, PID constant temperature, energy saving and power off from the water. <br>2、12V SAFE AND LOW VOLTAGE: Fish tank heating rod adopts 12V safety low voltage to prevent electric fish, when the heater is working, it will disconnect the power immediately after leaving the water to stop working. <br>3、SEPARATE CONTROLLER: Fish tank heater adopts separated controller, outside the tank to control the temperature. Switching display of °C and °F is available, and the control display is in full English, more convenient to view. <br>4、DUAL TEMPERATURE SENSING PROBES: Constant temp aquarium heater uses dual temperature sensors to monitor the tank in real time, 1h heating, 3h constant temperature, auto thermostat and real time power. <br>5、FREELY ADJUSTED: Aquarium heater uses intelligent frequency conversion technology, the power size is freely adjusted by the chip, always maintain the appropriate power constant temperature. 6、ABS SHELL: Submersible aquarium heater is made of ABS shell, safe and non toxic, no harm to water quality and aquatic plants and animals, freshwater and seawater can be used.1. Use the heating rod completely submerged in water, to prevent burning the rod body, burning melting the protective shell and other situations cause unnecessary trouble. <br>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 heated evenly. <br>3. It is not recommended to put the heating rod in the bottom filter, because some bottom filters do not have enough water level to submerge the rod, which may lead to accidents. <br>4. Please do not bury the heating rod in the bottom of the aquarium gravel and soil, because the gravel and water have different specific heat capacity, which will lead to damage to the heating rod. <br>5. The heating rod will work with a slight electrostatic (12V or less) is safe, please rest assured that the use.1 x <br> <br>Aquarium&nbsp;Heater<p>2 x Suction Cup</p><p>1 x Fixed Lanyard</p><p>1 x Adhesive Hook</p><p>1 x Instruction Book</p>
