Product Description
 
The Model RHB-CAC1 is a chilled mirror hygrometer specifically designed to monitor dew point in compressed air systems. It is a complete integrated system consisting of a microprocessor-based instrument, a chilled mirror dew point sensor, a sample flow meter with valve, and the necessary tubing and fittings. The wall-mounted enclosure allows for easy installation on any vertical surface.
