18 Years Factory Rh Transmitter - Corrosion-resistant IP65/IP66 housing used in compressed air systems – HENGKO
18 Years Factory Rh Transmitter - Corrosion-resistant IP65/IP66 housing used in compressed air systems – HENGKO Detail:
HENGKO temperature and humidity module 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.
Theory: current and inductance
Temperature range: -20~+100 ℃ -40~+125 ℃
Humidity range: (0~100)% RH
Features: Excellent long-term stability,
Probe housing: sintered stainless steel material, can be customized
