THC-01 Temperature and Humidity ControllerDetailed product description：

The THC-01 temperature and humidity controller adopts imported digital temperature and humidity integrated sensors, with high accuracy and good long-term stability. It monitors both temperature and humidity, automatically controls the load according to changes in environmental temperature and humidity, adjusts temperature and humidity to normal values, and has functions such as heating, cooling, dehumidification, and humidification. Suitable for temperature and humidity control in power high and low voltage switchgear, box type substations, high-grade constant temperature rooms (boxes), vegetable greenhouses, HVAC systems, refrigeration, pharmaceuticals, tobacco, chemical, warehousing and other places.
