HMZH-5 SF6 Analyzer

SF6 Gas Purity Analyzer,
Gas Leak Detection Device,
Portable SF6 Gas Leak Detector,

Product Description


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


  1. Dual-channel flow control design without fear of pressure fluctuation
  2. Utilizationþf high-precision electronic flowmeter,with flow overruns prompt
  3. Switch of trends of measuring objects,and real-time display of data
  4. Self-calibration function of zero and slope after startup
  5. Crossing-resistance interference technology of sensor
  6. Cleaning of residual gas in air circuit
  7. Lithium battery with ultra-large capacity,and dual purpose of AC/DC
  8. Large-capacity data storage,and USDB one-key data export
  9. Thermosensitive mute printer for rapid printing on the scene
