The DP39 series SF6 analyzer is an innovative and reliable series of products specially designed for the preventive testing of SF6 gas electrical equipment in power systems. The DP39 series is divided into five models: DP39-A, DP39-SF6, DP39-V5, DP39-EPSF6 and DP39-EPV5, which can better adapt to the SF6 gas test in various scenarios. The DP39 series can test data for up to 5 parameters, including moisture, purity, SO2, H2S, CO, depending on the selected model. The DP39-EPSF6 and DP39-EPV5 are two environmentally friendly devices that allow the measured ground gas to be pressed into a switchgear or an external cylinder. Each of these measures prevents SF6 gas from escaping into the atmosphere, better protecting the health of our field workers and caring for our planet.
