The water jacket is heated, the breeze circulates inside, and the temperature is more uniform.
Convenient operation, fixed value operation, automatic stop.
Dedicated function keys for temperature setting.
Auxiliary menu to realize overheating alarm, deviation correction and menu lock.
Vertical double air duct air jacket, centrifugal forced air supply from the turbine, more uniform temperature.
Overheating alarm, menu lock, low water level alarm.
