Temperature and humidity digital transmitter, wall mounted

The WM291 relative humidity transmitter is equipped with a replaceable Hygrosmart sensor module. This module allows you to easily replace the sensor part. The result is that the overall maintenance cost of the instrument has been greatly reduced, and the maintenance time has also been greatly shortened. highlight Third output optional Digital and Analog Output Standards Hygrosmart replaceable sensor module The temperature and humidity output signals can be selected through software Metric or imperial units of measurement can be selected through software Can provide calculation of absolute humidity, dew point, frost point, and mixing ratio output
