■ Product Overview
SF6 gas comprehensive tester is a set of SF6 humidity instrument, SF6 purity instrument, SF6 decomposition product instrument in one, the original to use three instruments to achieve the function, concentrated in one instrument. One on-site measurement can complete the detection of three indicators, greatly saving the gas in the equipment, a measurement saves 2/3 of the gas consumption, while reducing the user's workload, improve the work efficiency.
