new type SF6 decomposition Measurement catalogue

The SF6 gas Integrated test instrument can measure humidity (dew point) and purity in one unit, and concentrate the functions that need be realized by several instruments.In one time field measurement, tests two indicators, which greatly saves the gas in the equipment, reduces the user's workload and improves the work efficiency. The instrument can also combine humidity (dew point), purity, and decomposition substance, or measure any of these parameters.
