DewTran® II Chilled Mirror Hygrometer

The DewTran II chilled mirror hygrometer Series (patented technology) is a low cost, precision chilled mirror hygrometer that provides quick and accurate measurements of dew point, air temperature, humidity, or barometric pressure measurements. The hygrometer can be configured as a wall mount, duct mount, remote mount, or for flow through applications.The DewTran II chilled mirror hygrometer has user selectable, depending on options, unit displays (3 parameters) Dew Point (DP). Air temperature (T) and Relative Humidity (RH) or Barometric Pressure (BP), other units of measure are selectable (see page 3 of this spec sheet). The unit offers stable, accurate and repeatable measurements that are traceable to NIST.
