Testermeter- CWS86 Wall-Mounted Temperature And Humidity Transmitter
The CWS86 wall-mounted humidity and temperature transmitter fits into an 86 bottom box. Using Swiss SENSOR high-performance temperature and humidity sensor chip, the circuit adopts loop design, which avoids the problem of inaccurate measurement caused by internal temperature rise. Available with and without display.
Technical parameters Range: temperature -40~80°C humidity 0-100%RH (relative humidity) output: RS485, 4-20mA power supply: 5~28VDC, 9~28VDC
[In addition, we can provide customized products to meet the needs of customers in a short period of time, according to their application.]
Typical applications Suitable for temperature and humidity measurement in various indoor environments, hospital wards, clean rooms, HVAC, etc
