iSF6-1800S SF6 Multi Analyzer

Measure dew point, purity, decomposition byproducts of SF6 and pressure for electric equipment filled with SF6 gas.

iSF6-1800S multi analyzer can be used in GIS switches and other SF6 high-voltage insulated switchgear or divices, which filled with SF6 gas, to detect the moisture content, purity, decomposition products and chamber’s gas pressure. The analyzer is equipped with a unique gas processing system, which can recover and store the measured sample gas into the gas tank inside the instrument, and can pump the sample gas back to the gas chamber or container after the test, to achieve zero emission of SF6 sample gas.

The moisture detection of the iSF6-1800S adopts the classic cold mirror detection technology to improve the accuracy, stability, and reliability of long-term use. The purity of SF6 is detected by NDIR infrared optical technology, which can meet the higher requirements of purity detection for switching equipment. In addition, the instrument is equipped with a constant control system of pressure and flow to further ensure the accuracy and stability of the data in the detection of each function.

iSF6-1800S is the first choice in the market for SF6 gas measurement for it integrates advanced technologies and concepts and meets the requirements of users on environmental protection, functionality, accuracy, data processing, and human-machine interaction.
