The Edgetech Instruments Model DewTrak II dew point / humidity transmitter is an optical chilled 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.

The Model DewTrak II is available with the Edgetech Instruments Model DX chilled mirror dew/frost point sensor. With an integral PRT temperature sensor, the Model DX has a wide operating range and excellent temperature stability.

• Precision dew/frost point or relative humidity transmitter
• Primary method chilled mirror sensor requires no recalibration
• Rapid response with no false readings or accuracy drift
• Remote insertion or local wall mount sensor configurations
• Configurable analog outputs and alarm relays
• Bi-directional serial interface
• Powered by 24 Vdc.
