Humidity dew point meter.
Are used for accurate relative air humidity and temperature measurements.
PWT-101 is a pocketsize hygrometer connected with sensor without cable.
PWT-102 is connected with the sensor by cable.
PWT-103 additionally enables determining of dew point and is equipped with surface temperature probe.
