library.metergroup.com4TEV contains both a chilled-mirror dew point and a capacitance sensor. The capacitance sensor has a lower accuracy of ±0.015 a w than the dew point sensor, which has an accuracy of ±0.003 a w. To determine if volatiles are a problem, compare dew point readings to capacitance readings. If the dew point readings are >0.018 a w
