hygger Aquarium Heater,Submersible Fish Tank Heater with External Digital Display, Including Overheat & Leakage Protection and Temperature Sensor for Freshwater and Saltwater (500W for 60gal~90gal) - size: 500W for 60gal~90gal

About this item

• COMPOSED OF 4 MATERIALS: The outermost casing of aquarium heater is made of TA2 titanium alloy and coated with Teflon to resist corrosion and scaling, extending its service life. The interior features a quartz glass tube encasing a nickel-chromium alloy heating wire, ensuring rapid, even, and stable heat release for good temperature control
• EASY USE & CLEAN: The Teflon coating of submersible aquarium heater, provides a smooth surface, making it difficult for limescale and other substances to adhere. The shell-less design of this fish tank water heater makes it easy to clean
• EXTERNAL CONTROLLER: Three-digit display that shows both the set temp and actual temp. Fish tank heater with a working indicator light — red when heating, green when at constant temperature. The digital display can be switched between Fahrenheit and Celsius readings. Buttons are clearly and easy operation
• MANUAL TEMPERATURE CALIBRATION: If other thermometers show a significant discrepancy compared to the heater's real-time temperature reading, use the "ADJ" button to manually calibrate the heater's temperature offset until it matches the reference thermometer. The heater will then use this difference for water temperature detection, range is within ±5°F(°C)
• HEATER PARAMETERS: Consists of a heating rod without a casing + a built-in tempe probe + an external controller, suction cup fixation. 50W for 10gal~15gal, 100W for 16gal~26gal, 200W for 26gal~40gal, 300W for 40gal~60gal, 500W for 60gal~90gal. US standard:AC 110-120V/60HZ. Temperature range: 68°F~90°F / 20°C~32°C. Power cord length: 4.92 ft + 4.92 ft. Temperature accuracy: ±2℉ (±1℃)
• hygger Heater MATERIAL 1: The thermal conductivity of titanium alloy, combined with the scale-resistant advantage of the Teflon coating, ensures heat is rapidly dispersed throughout the entire aquarium, preventing localized overheating
• hygger Water Heater MATERIAL 2: The sturdy TA2 titanium alloy shell is impact-resistant. It protects the internal core from accidental damage during tank cleaning or hardscape adjustments. Even under significant external impact, the internal quartz glass serves as a final, reliable line of defens
• hygger Fish Heater MATERIAL 3: The quartz glass offers high thermal conductivity, efficiently transferring heat from the heating wire. Its low thermal expansion coefficient makes it highly resistant to cracking under sudden temperature changes
• hygger Aquarium Water Heater MATERIAL 4: The nickel-chromium heating wire is the heart of the heater. It features stable resistance, a high melting point, and an extended lifespan, delivering fast and uniform heating performance
