The Edgetech Instruments Model X3 chilled mirror sensor is specifically designed to measure the Dew/Frost point in demanding process and laboratory applications. It is available in multiple configurations to accurately measure very low dew/frost points in aggressive background gases. The Model X3 sensor’s minimized sample cavity results in rapid dry-down times, fast response and quick detection of upset process conditions. The sensor may be air or liquid cooled with a best-in-class range to –95°C frost point. The Model X3 sensor is used with Edgetech Instruments’ DewTrace, DewMaster and PDM75-X3 hygrometers for both fixed and field portable use, bringing chilled mirror technology to applications where drift free, high precision dew/frost point measurement was not previously possible.
