Hygger Submersible Aquarium Heater with LED Display for 240 Gallon Tanks

Accurate Temperature Control

Equipped with intelligent inverter technology, our aquarium heater maintains the water temperature at a precise 0.1°F accuracy, far surpassing traditional heaters. The built-in dual temperature control system operates in both Fahrenheit and Celsius, providing flexibility and precision. The temperature range is 63-94°F (17-34°C). Simply long-press the set button for 2-3 seconds to switch between scales.

Overheating, Low Temperature, and Dry Running Protection

Experience peace of mind with our heater's smart protection features: - Overheating Protection: When the water temperature exceeds 93°F, the error code “HH” is displayed, and the heater automatically shuts off. - Dry Running Protection: If the heater loses water, “Auto shut off” will flash, and the power will be cut to prevent damage. - Low Temperature Protection: When the water temperature drops below 59°F, the “LL” code appears, and the heater continues to maintain warmth.

Digital LED Display and External Temperature Controller

Our aquarium heater features a completely waterproof smart LED screen that clearly displays the current water temperature, set temperature, operating power, error codes, and operating status. A red light signals that the heater is in operation, while a white light indicates the heater has stopped to maintain the set temperature. Adjust the temperature by pressing the set button on the external controller.

Efficient and Explosion Proof

Constructed with explosion-proof quartz glass and thermally stable nickel-chromium wire, our heater efficiently transfers heat to the surroundings. The heat-resistant ABS material shell encasing the heater protects aquatic life from burns. For safety, unplug the power and wait 10-20 minutes before cleaning the tank or changing the water.

Built-in Temperature Sensor and Power-off Memory

The heater retains its settings, preserving the final temperature and operating power during a power outage. The 600W model is ideal for fish tanks up to 120 gallons, the 800W for 120-180 gallons, and the 1000W for tanks up to 240 gallons. These heaters ensure your aquatic environment remains stable and safe.
