Dew point transmitter meter is designed to measure the performance of drying systems for air, nitrogen, and other compressed gases. This Model is ideal for monitoring medical, commercial, and industrial applications including plastics resin dryers, breathing air, pneumatic tools, instrument air, and spraying/coating applications. It measures dew point by utilizing microprocessor circuitry to convert the sensor signals by the use of psychometric equations. Assembled in a rugged hand held IP-65 with quick disconnect tubing coupling and an internal sensor manifold. An orifice maintains line pressure for true pressure dew point readings.
