HMZH-5 SF6 Analyzer

Profile

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
