Outdoor temperature and humidity transmitter


Product description

The temperature and humidity sensor adopts high-precision temperature/humidity sensor and digital circuit. The duct-type PTFE filter and its unique high-humidity-resistant coating protect the product from long-term stable temperature and humidity collection in the air duct, and are protected from high humidity and harsh dust environments. It is used for air-conditioning or outdoor occasions where the measurement accuracy and response time of relative humidity are relatively high, and the measurement range covers 0~100%RH. Used in commercial buildings, cinemas and office buildings, laboratories with purification requirements, hospitals, electronics and pharmaceuticals, food plants, silk, paper industry, chemical and storage warehouses, cold storage computer rooms and museums, greenhouses, etc. Dew point temperature, dry and wet Reference measurement of bulb temperature.
