Hygger 600W Aquarium Heater for Freshwater and Saltwater Tanks

Accurate External Digital Controller

Using an external LCD high-definition display digital controller, this product can show the current water temperature, the set temperature, and the heating status. Its separation design enhances the aquarium heater’s waterproofness, ensuring hands remain dry while setting the temperature.

Temperature Control and Accuracy

Press and hold the setting button for 2-3 seconds to switch between Fahrenheit and Celsius. The temperature range is flexible, with adjustments from 59°F to 93°F. The accuracy is ±0.1°F, ensuring precise control.

Safety Features

Our aquarium heater includes a water temperature sensing system that provides a danger warning. The external controller displays error codes and issues alarm prompts, including Overheating-HH, Low temperature-LL, and Dry burning-L1. The smart chip regulates the heater to stop at 93°F and restart below 59°F. This ensures fish safety.

Heating Performance

Powered by stable nickel-chromium electric heating wire, the heater conducts heat through a thickened quartz glass explosion-proof tube. Encased in an ABS plastic shell, this design ensures stable, fast, and even heat dissipation. The water in the fish tank will quickly and safely reach the set temperature, reducing the risk of burns for fish.
