■ Product overview
The SF6 gas comprehensive tester is a combination of SF6 humidity meter, SF6 purity meter, and SF6 decomposition product meter. It combines the functions that can only be achieved with three instruments into one instrument. One on-site measurement can complete three index detections, which greatly saves the gas in the equipment, and one measurement saves 2/3 of the gas consumption, while reducing the user's workload and improving work efficiency.
