Hygger 600W Aquarium Heater with Digital Controller for Fresh and Saltwater

The hygger aquarium heater boasts two key safety features: an automatic power-off function and an audible alarm. Overheating protection is ensured through the built-in dual temperature probes within the heating rod. When the water temperature exceeds 94°F (34°C), the probes immediately detect the current temperature and automatically stop heating to prevent the fish from being cooked. Simultaneously, the controller displays the "HH" error code and flashes "Hi" to alert the owner, safeguarding the wellbeing of aquatic pets.

For low temperature protection, the heater is designed to detect water temperatures below 59°F (15°C). When this occurs, the heater will automatically begin heating the water, while the controller emits an audible alarm and displays the "LL" and "Low" error codes until the temperature rises above 59°F.

An anti-dry operation function further enhances safety. If the temperature sensor detects a lack of water, the heater will automatically cease heating to avoid dry burning. The controller will then sound an alarm, display the "L1" error code, and flash "Auto Off" as an additional precautionary measure. When changing the water, it is important to unplug the power and allow the heating rod to cool before removing it from the tank, to prevent potential burns from residual heat.

Suitable for both freshwater and saltwater aquariums, the hygger heater is available in a range of wattages to accommodate different tank sizes: 400W for 40-80 gallons, 600W for 66-135 gallons, 800W for 80-220 gallons, and 1000W for 130-260 gallons, with a temperature control range of 59-90°F.

The key to ensuring safety lies in the heater's built-in dual temperature probes, which alternately measure the water temperature to prevent both overheating and overcooling. The audible alarm and automatic shut-off functions provide additional layers of protection for the aquatic inhabitants.

hygger offers up to one year of after-sales support, addressing any issues that may arise. To select the most suitable wattage, the formula is: Fish tank (length x height x width) + 1000 x 2 = the required wattage.

The external digital controller features an LCD display, allowing for easy monitoring of the current and set temperatures, as well as the heating status. The separation of the heater and controller enhances waterproofing, and temperature adjustments can be made without getting hands wet.

With its stable, fast, and even heat dissipation, the hygger heater utilizes a nickel-chromium electric heating wire, a thickened quartz glass explosion-proof tube, and an ABS plastic shell to ensure efficient and safe heat transfer. The memory function ensures that the set temperature is retained even during power outages, making it a reliable choice for aquarium owners.
