RA912 SF6 Gas Analyzer

For determining the quality of SF6 gas

The RA912 multi-functional analyzer allows the determination of up to seis quality parameters with only one measurement:
  • SF6 concentration (%)
  • Moisture concentration
  • SO2 concentration (ppmv)
  • CO concentration (ppmv)
  • H2S concentration (ppmv)
  • Option: HF concentration (ppmv)
    RA-912F based on Thermal conductivity measuring SF6 purity of principle, only SF6 has spectral band absorption characteristics, interference from other components, to fully meet all kinds of electrical equipment using sulfur hexafluoride-filled with gases such as N2 or CF4; Unique advanced cross-sensitivity to measure the decomposition algorithm, a large number of laboratory data foundation, integration of linear algebra algorithms to calculate the results more accurate; Classic polymer film humidity measurement SF6, when ambient humidity changes, the moisture sensitive components of the dielectric constant is changed, a corresponding change in the output electrical signal. Using the principle of SF6 gas spectral absorption measurements, rapid, without the interference of other gas components to better meet the needs of the site.
      • SF6 purity mass ratio (g / g), volume ratio (mol/mol) switch at any time to display, can be directly controlled national standard, eliminating the volume and mass ratio conversion link.
      • Massive experimental data, based on real-time traffic temperature compensation.
      • Unique patented drying protection device.
      • Boot-up zero, the slope of the self-calibration.
      • Built-in gas filtration system
      • Each measuring gas path individually designed to ensure accuracy, independent regulation is more suitable for field use.
      • TFT touchscreen
      • Built-in printer
