MS-405BSF6 Dew Point Analyzer 

The SF₆ dew point analyzer is a portable, high-precision dew point meter manufactured with advanced technology, capable of accurately measuring the dew point temperature of gases. The perfect combination of a high-quality dew point sensor and intelligent electronic control technology allows it to be successfully applied to accurate dew point measurements under various environmental conditions.

Dew point measurement is based on the chilled mirror principle.  A semiconductor cooling element cools the mirror surface, causing water vapor in the measured gas to condense into water or frost. When the two-phase equilibrium of water in the gas is reached, the temperature of the mirror surface at this point is the dew point or frost point of the gas. Compared with other types of dew point meters, the chilled mirror dew point meter measures dew point temperature more accurately and also features good measurement repeatability, stable and reliable measurement results, and ease of operation.
The portable chilled mirror SF₆ gas dew point analyzer is a standard instrument for humidity measurement in power, gas, meteorology, electronics, petroleum, chemical, and metrology fields, and is an ideal choice for establishing humidity standard devices.

1. Adopts the chilled mirror equilibrium principle, eliminating measurement errors caused by hysteresis, resulting in high measurement accuracy.
2. Good repeatability, fast response speed, high sensitivity, and good stability.
3. 5-inch full-color high-resolution LCD screen displays instrument operating parameters such as dew point, mirror light intensity, and sample gas flow rate simultaneously. It can also perform conversions between dew point values and water concentration.
4. Features a maximum cooling capacity test function; low humidity rapid equilibrium function ensures the instrument can quickly and accurately measure the dew point.
