Hygger 300W Submersible Heater for 40-65 Gallon Tanks

Safety Features and Automatic Off Function

• Hygger Aquarium Heater with Safety Auto Off: If the water level drops too low, exposing the temperature sensor to the air, the heater automatically shuts off with a flashing "E1" error code and an audible alert to prevent overheating.
• Multi-Functionality: Enjoy a multi-functional external controller with easy-to-read digital displays.

Key Features of the External Controller

1. Digital Display: Real-time water temperature and set temperature are clearly shown on the digital display, available in both Celsius and Fahrenheit.
2. Color Indicators: A red indicator light signals when the heater is active, and a green light indicates the correct temperature.
3. Audio Alerts: An audio alert informs you when something is wrong, helping you respond quickly.
4. Easy Temperature Adjustment: Set the temperature without getting your hands wet, ensuring convenience and safety.

Corrosion-Resistant Design and Protection

• Integrated Protective Guard: The integrated protective guard shields fish and other livestock from burning, ensuring the safety of your aquatic pets.

Temperature Monitoring and Alerts

• High and Low Temperature Alerts: The heater auto-shuts off and emits a beeping alarm if the water temperature goes below 59°F or above 95°F. The system resets when the temperature returns to the controlled range between 59°F and 93°F.
