Description

This versatile handheld meter provides an ideal combination for spot-checking anything from cleanrooms to air conditioning ducts, and can also be used for field calibration of installed sensors.  In addition to displaying the humidity and temperature, it also calculates dew point, wet bulb temperature, absolute humidity and mixing ratio.  These features, plus a fast response time, make the HMI41/HMP46 combination the ideal choice for the most demanding applications.
