The SF6 gas analyzer is mainly used to measure the purity (percentage content) of SF6 gas in the mixture of SF6 and air, SF6 and N2, and to check the purity (percentage content) of SF6 gas in SF6 equipment (cables, switches). It can also be used in applications with several background gases (special requirements need to be specified).

SF6 comprehensive analyzer is specially used for index detection of insulating gas in SF6 electrical equipment, and adopts the high-performance sensor for measurement of dew point, purity and decomposition product to guarantee the accurate and stable test results. Equipped with the unique gas circuit structure, it adopts the high-precision electronic flowmeter for full-automatic detection so that the SF6 can be more accurate in gas analysis. Three indexes can be detected via one-time measurement, which greatly reduces the workload of users and improves the work efficiency
