Dew Point Meter

Dew Point Meter Temperature Meter  

            A dew point meter is an instrument that can directly measure the dew point temperature. Let a mirror surface cool down in the humid air of the sample until the moment when dew drops (or ice crystals) appear on the mirror surface, measure the average temperature of the mirror surface, which is the dew point (frost) temperature. It has high humidity measurement accuracy, but it needs a highly polished mirror surface, a high-precision temperature control system, and a highly sensitive dew drop (ice crystal) optical detection system. During use, the pipes that inhale the sample air must be kept clean, otherwise the impurities in the pipes will absorb or release moisture and cause measurement errors.
