Adjustable and Accurate Temperature
The mini heater starts to heat, and the red light is on when the water temperature is lower than the set temperature, while it stops heating and the green light is on when it reaches the set temperature. Its variable setting range is 63-94℉/ 17-34℃, and the accuracy is ±1°F.

Automatically stop heating if the water temperature exceeds 34°C/94°F, and the controller will flash the water temperature until the water temperature drops below 34°C/94°F.

Automatically retain the previous setting when the heater is restarted.

Safe & Explosion-proof
