GDSF-411CPD SF6 Gas Comprehensive Analyzer
GDSF-411CPD SF6 gas comprehensive analyzer is a portable device designed to measure SF6 gas dew point, purity and decomposition product. The core component with chilled mirror method is used to test dew point, European sensor with infrared method to test SF6 gas purity and electrochemical sensor from Membrapor to test SF6 gas decomposition product. Besides, we also adopt professional hardware chips and excellent software algorithms of STMicroelectronics.
