Product description
1. Temperature and humidity controller uses dedicated microprocessor, SMT mounting technology and high precision temperature and humidity sensors. Compact, reliable performance, high- precision measurement and control thetemperature and humidity, strong anti-jamming ability, controls are simple. Can bewidely used in industry, agriculture, medicine, chemical industry, warehouse, etc where temperature and humidity measurement and control are needed.
2. The controller with temperature, temperature alarm, heater disconnection alarmfunction, communication function, widely used in automation and controlapplications.
Note: The alarm and disconnection alarm output contact for the same.
