Oil Filled Pressure Gauge

Mahalaxmi Instruments offer "MASTER" make Oil filled pressure gauges. In Oil filled pressure gauges we filled it with lubricant like oil so that it can be protected from environmental conditions and vibrations. Because of this we can increase the life of pressure gauges.

By this mechanism accuracy of Oil filled pressure gauge is more than the other regular pressure gauges. These gauges are subjected to aggressive environmental condition, Vibration proof, suitable for any type Burdens.
