产品描述：

Optical Chill Mirror Hygrometer
The EdgeTech Model DewTrak II dew point / humidity transmitter is
an optical chill mirror hygrometer designed to continuously measure
the moisture content in gases. The instrument is powered by 24Vdc.
The DewTrak II uses the chilled mirror dew point temperature
condensation principle to determine the water vapor concentration in
gas mixtures, and a platinum resistance thermometer to accurately
measure that temperature. Outputs include 4 to 20mA, 0 to 5 Vdc,
or 0-10Vdc and an RS232 serial port as well as electrically isolated
relay contacts.
