Safety: A Core Value in Design

You can easily monitor and adjust the water temperature in real time. The temperature range varies from 63-94℉ (17-34℃) with an impressive accuracy of ±1°F. By long-pressing the button for five seconds, you can switch between Fahrenheit and Celsius. During operation, a red light indicates heating, while a green light signifies that the desired temperature is maintained.

Designed with an Automatic Constant Temperature Function, the heater stops once the water reaches your set temperature and resumes heating when it falls below that mark, ensuring your fish always enjoy an optimal living environment.

Product Features:

• Explosion-Proof Quartz Construction: The 300W Aquarium Heater employs state-of-the-art aerospace technology, featuring two explosion-proof quartz glass tubes with high-temperature resistant heating wires. Encased in V0 grade ABS flame-retardant plastic, it is IP68 waterproof and resistant to corrosion and high temperatures, enhancing the heater's overall strength.

• Overheating and Out-of-Water Protection: The heater is equipped with a safety mechanism that prevents overheating and operates effectively. If the heater is 2 inches (5 cm) above the water's surface, it will automatically halt heating. The controller will indicate an "E1" error and sound an alarm until re-submerged. Additionally, if the water temperature exceeds 34°C (94°F), the heater will stop functioning and display "HH," alerting you until the temperature drops to acceptable levels.

• Precise Temperature Control System: Featuring dual temperature sensors on the heating rod, along with an upgraded temperature probe, this heater guarantees accurate water temperature readings. With an automatic constant temperature feature, it maintains a temperature accuracy of ±1°F. When the water temperature surpasses the set level, the heater ceases operation, while it will restart once the water cools down below the desired temperature.

• Digital LED Controller: The heater allows you to set the desired temperature using "+" and "-" buttons, with a simple long press to toggle between Fahrenheit and Celsius. The LED display conveniently shows both the current and the set temperatures. Red indicates heating, and green denotes a constant temperature. The heater also features a memory function that retains previous settings upon restart, eliminating the need for reconfiguration.

• Versatile Applications: Suitable for fish tanks ranging from 20 to 80 gallons, this 300W heater measures 6.8 inches in length and operates at 110-120V. Select the appropriate aquarium heater based on its specifications. It is compatible with both freshwater and saltwater tanks, turtle habitats, and other aquariums. Easy installation is facilitated by strong suction cups on the heater guard, allowing secure attachment to tank walls or bottoms.
