Adjustable Temperature Small Aquarium Heater with LED Display

Dual-Purpose Multifunctional Quartz Heater

Unique Design and Functionality - Protective Shell with Suction Cups: Use the protective shell equipped with 2 strong suction cups to ensure safety. This feature prevents burns and securely holds the heater in place. - Single Quartz Tube Body and Tube Body Suction Cup: The quartz tube body, complete with an additional suction cup, provides stability and easy installation. This design ensures the heater remains in position without the need for a protective shell, saving space.

Double Digital Display External Controller - Real-Time and Set Temperature Display: Our controller displays both real-time and set temperature simultaneously, ensuring you maintain precise water temperature control. - Temperature Range: Set the temperature from 59°F to 94°F (15°C to 34°C). - Unit Conversion: Hold down the button for 8 seconds to convert between Fahrenheit and Celsius for flexibility in usage.

Automatic Safety Features - Out of Water Power-Off: When the heater is more than 1.5 inches out of water, it automatically powers off, and a digital controller displays error code E1. Once submerged, the error code automatically clears. - High Temperature Automatic Power Outage: If the water temperature exceeds 95°F (35°C), the heater stops heating and displays error code HH. When the temperature drops below 94°F, the temperature display returns to normal.

Additional Precautions - Water Circulation: Use with a water circulation product for more accurate temperature detection. - Regular Cleaning: Disassemble and clean the heater tube every 1-2 weeks to maintain optimal performance. - Safe Removal: Allow the heater to cool for 15 minutes before removing it from the water to prevent burns.
