Density Meter With CE Certificate use in high voltage transformer substation sf6 meter

Description:

   Density monitor sf6 gas is an economical and reliable way to monitor SF6 gas density and leakage over a wide temperature range.

  These instruments are used to monitor SF6 gas density in sealed tanks. They are applied to indicate gas density and to provide a signal outputs when the density reaches preset threshold values. They are designed to monitor Medium Voltage systems.
