Top Quality Rh Probe - IP67 wireless RHT22 High-temperature dryers sensor 316 stainless steel temperature humidity dew point transmitters sensor detective probe ( dustproof housing ) – HENGKO
Top Quality Rh Probe - IP67 wireless RHT22 High-temperature dryers sensor 316 stainless steel temperature humidity dew point transmitters sensor detective probe ( dustproof housing ) – HENGKO Detail:
HENGKO temperature and humidity transmitter sensors stainless housing adopt high precision RHT series sensor equipped with a sintered metal filter shell for large air permeability, fast gas humidity flow and exchange rate. The shell is waterproof and will keep water from seeping into the body of the sensor and damaging it, but allows air to pass through so that it can measure the humidity (moisture) of the environment. It has been widely used in HVAC, consumer goods, weather stations, test & measurement, automation, medical, humidifiers, especially perform well in an extreme environment like acid, alkali, corrosion, high temperature and pressure.
