VCRAZE Aquarium Heater 200W Fish Tank Heater with External Thermostat (Dual Digital Display), Turtle Heater for Tanks 20-40 Gallons, Dry-Run/Overheating Protection and Memory Function

INVERTER TECHNOLOGY - Our fish tank heater uses cutting-edge inverter technology for quicker water heating. This ensures efficient maintenance of a consistent water temperature. Thanks to this technology, the heater also enjoys a longer life-span than the traditional aquarium heaters.

PRECISE EXTERNAL THERMOSTAT - The aquarium heater comes with built-in chips to provide an accurate water temperature up to 1F. This makes it considerably more precise than the traditional knob-controlled heaters. The external thermostat's digital display showcases 2 readings - the current and set temperatures, simplifying its operation.

SMART PROTECTION SENSORS - The fish heater's multifold sensors prevent operation when the water level drops below the minimum (DRY-RUN) or when the water temperature goes over 95F (OVERHEAT). A MEMORY FUNCTION is also in place. In the event of a power outage, the heater reverts to the last setting when power returns, helping you avoid "cooking fish"!

PREMIUM MATERIALS - The heater is made of sturdy nickel-chromium heating wire and highly conductive sand, all encased within a shatterproof quartz glass tube, attesting to its top-notch quality. Its multiple-slotted ABS plastic casing also shields your fish from burns.

VERSATILE USES - Our heater is suitable for both fresh and seawater. Besides serving as an aquarium heater and turtle tank heater, it can also be utilized for pet fountains and plant seedlings.
