The device has low cost, simple manufacture, high reliability and high precision (plus or minus 0.3 degrees, depending on the sensitivity of the electric contact thermometer ). A person with a slight electronic technology base can install it and have a power failure alarm. After the power failure, the biogas, charcoal and hot water can be heated. If the actual temperature exceeds the required temperature, the alarm will sound. This thermostat is suitable for large, medium and small electric incubators and various thermostats.
