High Quality for Humidity Sensor Industrial - HENGKO SD123-T10 waterproof Temperature and Humidity Transmitter 485modbus for environmental measurement – HENGKO
High Quality for Humidity Sensor Industrial - HENGKO SD123-T10 waterproof Temperature and Humidity Transmitter 485modbus for environmental measurement – HENGKO Detail:
HENGKO analog 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.
