According to the requirements of JJG499-2004 "Verification Regulation for Precision Dew-Point Meters" and JJF1272-2011 "Calibration Specification for Capacitive Hygrometers", the dew-point meter verification/calibration system requires equipment including dry gas sources, high-precision low-humidity generators, and chilled-mirror precision dew-point meters.

The Fermetrics DCS high-precision dew-point meter verification system provided by York Instruments adopts Edgetech's Dew Master high-accuracy chilled-mirror dew-point meter as the standard reference instrument, combined with the DC2000 low-humidity generator as core equipment, forming a complete temperature and humidity metrological verification system. Using the chilled-mirror dew-point meter as the standard instrument.

This system achieves extremely high measurement accuracy, meeting the requirements for metrological verification, scientific research, and product testing applications, enabling the dew-point verification system to reach a measurement accuracy of ±0.1°C dew point.
