Description

SF6 is a greenhouse gas that is 23,900 times more potent than CO2, and it remains stable in the atmosphere for up to 3,200 years. To protect the atmospheric environment, SF6 was listed as one of the six greenhouse gases prohibited to be discharged into the atmosphere in Kyoto Protocol issued in 1997. It is vital and mandatory that SF6 is collected and stored after measurement, for EU and IEEE have promulgated regulations of SF6 gas use and treatment to reduce the emissions into the environment. It is also important to collect and store the used SF6 gas after measurement for SF6 field test staff safety.

iSF6-1800S multi-analyzer can be used in GIS switches and other SF6 high-voltage insulated switchgear or devices, 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 an on-board cylinder, The equipment can then pump the sample gas back to the gas chamber or container after the test and achieve zero emission of SF6 sample gas.

The moisture detection of the iSF6-1800S adopts the classic chilled mirror detection technology to improve the accuracy, stability, and reliability for long-term use. The purity of SF6 is detected by MEMS 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 measurement of each function.

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

iSF6-1800S SF6 gas multi-analyzer is installed in a rugged and waterproof ABS integrated portable case that is easy to transport and move while protecting the internal system, making it an ideal environmentally friendly analyzer.
