Description

iSF6-1800E is designed for measuring dew point, purity, ecomposition products and chamber pressure for GIS switchgear and high voltage switchgear equipment. It can recovery used SF6 gas in an on-board cylinder. The used gas can be pumped back to the original equipment under test after analyzing. iSF6-1800E has integrated advanced measuring cells, i.e. thin-film polymer technology for SF6 dew point measurement, non-dispersed Infrared (NDIR) 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.
