DewTrak II Chilled Mirror Transmitter
Compact, Direct-Reading Dew Point Transmitter for OEM and Process Integration
Starting at: $3,150.00
The DewTrak II Chilled Mirror Transmitter delivers high-precision, drift-free dew point measurement in a compact format built for integration. Ideal for OEM installations, environmental chambers, gloveboxes, and other process-critical applications, DewTrak II uses the chilled mirror principle to provide direct, NIST-traceable measurements—without relying on calculated estimates or sensors prone to drift. With multiple form factors, digital/analog outputs, and cable runs up to 100 feet, it’s a trusted solution for automated systems, controlled environments, and tight installation footprints that don’t require a local display.

Q: What makes the DewTrak II different from a full chilled mirror hygrometer?
A: DewTrak II is a transmitter—it offers the same chilled mirror measurement accuracy but is built to send signals to external control systems, without a local display interface. If you need a full unit, we recommend you consider our DewMaster Chilled Mirror Hygrometer.
Q: What’s the difference between the fan-cooled and liquid-cooled versions?
A: Fan-cooled sensors allow for temperature depression up to 90 °C. Liquid-cooled versions extend the depression further, down to –80 °C dew/frost point.
Q: How often is calibration required?
A: Annual calibration is typical. All calibrations are performed in our ISO/IEC 17025-accredited lab and are fully NIST-traceable.
