OEM Best Sf6 Breaker Maintenance Factories – GDSF-311WPD 3-in-1 SF6 Gas Analyzer – HV Hipot

General Information

GDSF-311WPD (GDSF-411WPD) is an ideal instrument when it is necessary to test water content, purity and decomposition products of SF6 gas. The core component of dew point test is DRYCAP®  series sensors produced by Finland Vaisala company. The infrared principle SF6 gas purity testing sensor manufactured by European Sensor Company is used to test the purity of SF6 gas. The electrochemical sensor manufactured by Mombabo Company in Switzerland is used as the sensing element for the test of SF6 gas decomposition products. With professional hardware chips and excellent software algorithms of STMicroelectronics, we have produced a new generation of 3-in-1 gas analyzer.
