Dew Point Meter


Portable Dew Point Meter With Shaw Sensor is designed to measure the performance of drying systems for compressed air, nitrogen,transformer and other compressed gases. This Portable Dew Point analyzer Model is ideal for monitoring medical, commercial and industrial applications including plastics resin dryers, breathing air, pneumatic tools, instrument air, and spraying/coating applications. You can use this Dew Point analyzer continuously up to 90 hours without low battery indication.

Dew Point Meter analyzer measures dew point by utilizing microprocessor circuitry to convert sensor signal by the use of psychometric equations. Assembled in a rugged hand held IP‐ 65 protected plastic enclosure and equipped with quick disconnect tubing couplings and an internal sensor manifold.Dew point meter used for compressed air and nitrogen gasses.
