Aquarium Heater for Small Fish Tanks, Adjustable Temp with LED Display Thermostat

🌡️ The Dual Purpose Multifunctional Quartz Heater offers two distinct usage options. When used with the protective shell, it provides a safe and convenient heating solution. Alternatively, the single quartz tube body can be utilized independently. The shell is equipped with 2 strong suction cups, and the tube body features a suction cup as well, allowing for flexible positioning. The protective shell helps prevent accidental burns, while not using the shell can reduce the overall space occupied by the device.

🌡️ The Dual Digital Display External Controller offers a range of functionalities. It simultaneously displays the real-time water temperature and the set temperature. The button on the controller allows users to adjust the temperature between 59°F and 94°F (15°C and 34°C). The LED indicator lights provide visual cues, with the red light indicating that heating is in progress and the blue light signifying that the set temperature has been reached. By pressing and holding the button for 8 seconds, users can easily convert the temperature readings between Fahrenheit and Celsius.

🌡️ The device is designed with an "Out of Water Power Off" feature. If the heater is lifted more than 1.5 inches above the water surface, the heating rod automatically shuts off, and the digital controller displays the error code E1. The error code is automatically cleared when the heater is submerged back into the water.

🌡️ Additionally, the Quartz Heater is equipped with a "High Temperature Automatic Power Outage" function. When the water temperature exceeds 95°F (35°C), the heating rod automatically stops heating, and the controller displays the error code HH. The normal water temperature display is automatically restored once the water temperature drops below 94°F.

🌡️ Regarding the precautions for use, the product comes with a one-year quality assurance, providing users with the confidence to purchase. It is recommended to use the heater in conjunction with a water circulation product for more accurate temperature detection. When using the device, it is essential to first place it in the water and then turn on the electricity. Before removing the heating rod from the water, ensure that it has completely cooled down.
