973 Dew Point Mirror - Process Insights

973 Dew Point Mirror - Process Insights

The Model 973 Dew Point Mirror is a portable Instrument equipped with an integral measuring head for both spot and continuous measurement of frost/dew point and temperature in air and gas. Based on the chilled mirror principle, the 973 provides fundamental, drift free and precise humidity measurement. The 973 has no need for either humidity sensor replacement or calibration adjustment. Unlike sensor-based systems, routine maintenance is conveniently limited to occasional mirror cleaning. Users can self-check instrument calibration stability using the integrated Ice-Test function.

Features:

Fundamental drift free humidity measurement
Integral frost/dew point measuring head
Internal sample pump
Optimal Response Injection System for fast measurement
Pressures up to 20 bar
Intuitive, easy to use LCD touch screen user interface
