Factory source Temperature And Humidity Meter - Large air permeability 4-20ma agriculture temperature and humidity sensor probe (RHT series) with IP65 waterproof sintered filter probe housing – HENGKO
Factory source Temperature And Humidity Meter - Large air permeability 4-20ma agriculture temperature and humidity sensor probe (RHT series) with IP65 waterproof sintered filter probe housing – HENGKO Detail:
HENGKO digital 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

Large air permeability 4-20ma agriculture temperature and humidity sensor probe (RHT series) with IP65 waterproof sintered filter probe housing
Product Description
1. Large air permeability, fast gas humidity flow and exchange rate, uniform divergence. it is far superior to other peer products with the optimization of a special processes in HENGKO.
2. Excellent ability of anti-dust, anti-corrosion and waterproof（IP65）
3. Protecting PCB modules from dust, particulate pollution and oxidation of most chemicals to ensure sensors a long-term stable operation, higher reliability and long service life
4. Remarkable performance in harsh environments such as small space, long-distance space, pipe, trench, wall pass mounting, high-pressure space, vacuum chamber, test chamber, large flow mediums, high humidity area, high temperature and heat environment, hot drying process, dangerous zones, explosive environment containing explosive gas or dust, etc
5. the HENGKO stainless steel porous housing for sensor probe, have accurate pore size, uniform and even-distributed apertures. Pore size range: 5μm to 120 microns; it has good filtration dustproof and interception effect, high filtration efficiency. The pore size, speed of the flow and other performances can be customized as requested; Stable structure, particles are tightly bound without migration, almost inseparable under harsh environment.
