The CM-RO-DEWTRAN-HB is a temperature controlled 2 stage chilled mirror hygrometer suited to measure elevated dew points up to 95°C in a non-condensing environment. Dew point measurement range is from -30°C to 95°C. The chilled mirror uses a fundamental principle to accurately measure the dew point/frost point in a gas sample. It is typically used as a reference standard for dew point over the measurement range. It is very responsive and repeatable to +/-0.05°C and easy to maintain.

The CM-RO-DEWTRAN-HB has a built in automatic reference cycle (ARC) method that balances the optical signal for temperature change and mirror contaminants. The unit includes a heated stainless steel sintered filter and is rated to filter particles down to 7 microns. The filter element is easy to remove and clean.

The temperature inside the sensor housing is controlled via the RS232 communications. Unit comes with a 10 ft heated hose and NIST Certificate.
