iSF6-1800E SF6 Multi Analyzer

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

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.

iSF6-1800E is designed to measure dew point, purity, composition products and chamber pressure for GIS switchgear and high voltage switchgear equipment. It can recover used SF6 gas in an on-board cylinder. The used gas can be pumped back to the original equipment undertest after analyzing. iSF6-1800E has integrated advanced measuringcells, i.e. thin-film polymer technology for SF6 dew point measurement and MEMS technology for SF6 purity measurement. The unique way of sampling, high precision flow control, and touch screen operation improve the accuracy and ease of use.

iSF6-1800E 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.
