ZMJ60R Density Monitor
ZMJ60R Density Monitors is used to monitor the density of gas in closed containers, and can be widely used in medium voltage switchgear and ring network cabinet. It can display gas density on site, and reliably output SF6 gas density signal for remote monitoring and monitoring. It can be used in the new substation building and renovation and upgrading of existing substation.
