The Model DPS3 is a heated dew point hygrometer that can measure dew/frost points up to 95°C (203°F) and as low as -35°C (-31°F). This integrated system includes a microprocessor based electronics, a chilled mirror dew/frost point sensor, a sample flow metering valve, a 3 foot heated sample line, assorted tubing and fittings; all contained in a heated, temperature controlled NEMA-4 enclosure.

The heated system allows the measurement of high dew points that are above ambient temperature. Without the heated system, condensation would occur and measurements could not be taken.

The DPS3 is ideal for applications including measuring the dew/frost point or moisture content in furnaces, heat treat systems, fuel cells, chemical reactors, fluidized bed dryers, centrifuges, getters, glass plants, RTP, and heated MAP systems.

The two-stage, primary method chilled mirror dew/frost point sensor in the DPS3 provides an accurate and fundamental measurement of the dew point of the sample gas.
