High definition Waterproof Humidity Sensor - waterproof porous stainless steel relative humidity probe RHT20 35 – HENGKO
High definition Waterproof Humidity Sensor - waterproof porous stainless steel relative humidity probe RHT20 35 – HENGKO Detail:
HENGKO soil moisture module 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, medical, and humidifiers, especially performing well in extreme environments like acid, alkali, corrosion, high temperature, and pressure.
HENGKO digital temperature humidity detector probe module has excellent performances of high precision: temperature +-0.1°C, humidity +-1.5%RH, multiple outputs: RS485, 4-20mA, 0-10V, 0-5V, switching value ……, various RHT sensor optional, wireless and wired, various probes optional, various sensor housings optional.
HENGKO temperature and humidity probe detectors can be applied in various fields: telepoint base stations, electronic control cabinets, production sites, storehouses, machine rooms, greenhouses, animal farming, medicine stock and etc. The metallic package enables it to deal with the very dust or other severe circumstances. the wall-hanging style makes it easy to install. split type temperature and humidity sensor made with an IP66 protection grade high-tightness stainless steel sensor porous housing, it can be directly used in harsher environments, such as open-air, sand/dust environment, high humidity environment, corrosive environment, etc.
