Product Overview
YGM803 relative humidity switch adopts imported polymer film capacitive humidity sensor, which has long-term stability and good reliability. The sensor has strong anti pollution ability, and is very suitable for industrial occasions with harsh environment.
YGM803 sensing and transmitting parts are highly integrated, with the advantages of rapid response, strong anti-interference ability, high accuracy, and excellent cost performance.
YGM803 has LCD display function, which can directly display the current temperature and humidity, more user-friendly.
YGM803 has switching value output function. With buttons, the switch alarm parameters can be set on site, which is easy to operate.
There are three installation methods: wall mounted, pipe mounted and 86 cassette mounted.
There are two kinds of filters: plastic grid filter and stainless steel filter. Users can make matching selection according to their needs.
This product is suitable for building automation, HVAC, biopharmaceutical, semiconductor and microelectronic industries, environmental control and other fields.
