The DewTrak™ Portable Humidity Meter, Model 100, is a very versatile instrument. It is a hand-held digital hygrometer that combines the inherent accuracy, reliability, and long-term stability of optical chilled mirror technology with the convenience of a battery-operated micro-processor-based unit.

A battery pack that consists of standard primary cells is attached to the back of the instrument. The Model 100 Portable Humidity Meter can also be used for continuous monitoring when it is equipped with the Battery Eliminator option that permits 115-230 VAC, 50/60 Hz operation. The basic instrument measures dew point only in ºC or ºF (switch selectable). Options are available that permit ambient temperature (ºC or ºF), % relative humidity, wet bulb temperature (ºC or ºF), or other psychrometric variables.

The instrument incorporates a patented electro-optic sensing scheme and a unique new control algorithm that:
