The CMDP overviews
The CMDP series is a family of low-cost dew point chilled mirror transmitter that can be
configured as a duct, wall, pipe, or an OEM unit. The unit offers stable, accurate and
repeatable measurements that are traceable to NIST. Available air temperature option for wall
and OEM configurations. Settable service cycles for balancing and cleaning the mirror. The
CMDP is a primary measurement using a fundamental principle to measure the dew point very
accurately. Simple maintenance to cleaning the mirror requires using a wetted cotton swab to
restore the transmitter to normal operation. Because of its construction, the customer can enjoy
a long life of excellent performance.
