This document describes a Dew Point Transmitter Meter that measures the dew point of compressed gases like air, nitrogen, and other industrial gases. It utilizes microprocessor circuitry and psychometric equations to convert sensor signals into dew point readings. The meter is assembled in a rugged hand-held housing with quick disconnect fittings and an internal sensor manifold. It provides analog outputs and can measure dew points from -100°C to +30°C across various industrial applications.
