The Roscid Technologies CM10 chilled mirror hygrometer is a low-cost dew point chilled mirror transmitter that can be configured as a duct, wall, or pipe unit. The CM10 provides stable, accurate and repeatable measurements that are traceable to NIST and the wall configuration has the additional option for temperature measurement.

The CM10 has settable service cycles for balancing/cleaning and simple maintenance of cleaning the mirror using a wetted cotton swab to restore the transmitter to normal operation.
