The Artech DPA10 is used for continuous measurement of the Dew Point of air and gases in Gas Plants, Annealing Furnaces, Compressed Gases, Medical Gases, Natural Gas, Drying Systems and Power Generation. The instrument is provided with a by-pass valve to isolate the sensor when not in use, thereby ensuring fast response on re-startup. With the flow indicator the user knows when the sample gas is flowing The regulator controls the pressure, thus preventing damage of the sensor path by excess/fluctuating pressure..
