SR-308 Mini LED Display Aquarium Heater

• Aquarium Heater for 5-15 gallon: Our aquarium heater utilizes an explosion-proof quartz heating tube, which is safer and more reliable compared to traditional coil heaters.Suitable for 5-15-gallon fish tanks. It operates at a rated voltage of 110-120V. Please consult the size chart to select the appropriate heater wattage.
• LED Temperature Display: The water temperature is continuously displayed on the external controller. There is no need for additional aquarium thermometers. Temperature sensors ensure accurate temperature measurement, and you can switch between Celsius and Fahrenheit temperature units. [Accuracy：±3°F]
• Aquarium Heater 10-gallon Tank Easy to install: Due to its compact design and strong suction cups, this heater can be easily installed at any location within your aquarium. It is suitable for both freshwater and saltwater environments.
• Safety features: For safety, the heater includes overheat protection, which automatically stops heating in case of overheating or low water levels. If the temperature becomes too high, "HH" will be displayed on the remote control. Also equipped with dry-burn protection, meaning it won't immediately stop working after leaving the water surface. It will automatically cease operation after a while of being away from the water surface
• After-sales service: The heating rod must be completely immersed in water.Suitable for 5-15-gallon aquariums.

• Two sizes are available, with lengths of 4.7 inches and 6.3 inches, suitable for any aquarium and easy to conceal within the tank.

• Package: 1 heater with an external controller, 2 suction cups, 1 user manual

• Automatic constant temperature, 25W, 50W, 75W, 100W suitable for fish tanks of 1-25 gallons.
• Easy temperature setting: Press the "+/-" buttons to set the temperature. After setting to the target temperature, it will return to the current temperature display. If the temperature exceeds 99°F, heating will stop, and the remote control will display "HH."
• Switching temperature units: According to your preference, switch temperature units by simultaneously pressing the "+ and -" buttons to switch between Fahrenheit (℉) and Celsius (℃).
• Start heating: If the water temperature is below the set value, the heater will activate, and the red indicator light will illuminate. The green indicator light indicates that the water has reached the set temperature and heating has stopped.
• Indicators

Red: Heating

Green: Temperature constant

Lack of water protection

• Lack of water source protection: Built-in water level sensor. If the heater lacks water or the fish tank is low on water, the heater will automatically stop heating. When the heater is fully immersed in water, it will resume operation.

Aquarium Heater fully immersed in water, please place it in an area with greater water flow to promote temperature equilibrium

Versatile in application

• Tropical Fish Farming: For tropical fish species that require maintaining a constant water temperature, a fish tank heater is essential. This helps simulate the optimal temperature they need in their natural environment.
• Hatching and Fry Rearing: During the hatching of fish eggs and the rearing of fry, maintaining the appropriate water temperature is crucial for the health and development of the fish. A fish tank heater can provide a stable temperature environment.
• Cold Climate Regions: In cold climate areas, a fish tank heater can help prevent the water temperature in the tank from dropping to levels detrimental to the fish.
• Aquarium Temperature Maintenance: For freshwater or saltwater aquariums that require maintaining a constant water temperature, a fish tank heater is a common device.
• Breeding Projects: In fish breeding projects, especially for species sensitive to temperature, a fish tank heater can provide the necessary environmental conditions.
