HENGKO temperature and humidity transmitter sensors' stainless housing adopts 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, and medical, and humidifiers, and especially perform well in extreme environment like acid, alkali, corrosion, high temperature, and pressure.
