  • GDP-713PM SF6 Gas Dew Point Tester (Chilled Mirror Method)

    GDP-713PM SF6 Gas Dew Point Tester (Chilled Mirror Method)

    GDP-713PM Portable Chilled Mirror SF6 Gas Dew Point Tester is specially designed for SF6 gas micro moisture detection. The perfect combination of high-quality dew point sensor and intelligent electronic control technology makes it successfully applied to accurate measurement of dew point under various environmental conditions.

    The dew point measurement is based on the principle of chilled mirror. The water vapor in the measured gas is condensed into water or frost on the mirror surface through semiconductor cold reactor cooling. When the two-phase equilibrium of water in the gas is reached, the temperature of the mirror surface is measured at this time, that is the dew point or frost point.

    Compared with other forms of dew point meter, the chilled mirror dew point meter measures the dew point temperature more accurately, and at the same time has the characteristics of good measurement repeatability, stable and reliable measurement results, and easy operation.

    GDP-713PM portable cooling method SF6 gas dew point meter is a standard instrument for humidity measurement in the fields of electric power, gas, meteorology, electronics, petroleum, chemical industry, measurement, etc. It is an ideal choice for establishing a humidity standard device.
