DM60R Remote-Transmission Density Monitor

These instruments are used to monitor the density of SF6 gas in sealed tanks. They are applied to indicate the gas density and reliably output SF6 gas density signal for remote monitoring. They can be widely used in monitoring medium voltage system. They can provide multiple solutions to support new substations and the intelligent transformation of existing substations.
