OMEGA’s PGM series gauges are suitable for corrosive environments in chemical, petro-chemical, refining, power, marine and food and pharmaceutical processing applications. The PGM series comes in a 63 mm (2½') or 100 mm (4') case, features all stainless steel construction and is environmentally protected to IP65.
The PGM series can also be liquid filled in the field. Liquid filled pressure gauges provide users with a number of advantages in certain applications. They are ideally suited for uses on equipment where excessive vibration and pulsation are encountered such as pumps, compressors and machine tools etc. The liquid fill minimizes the effect of these severe environments, protects the gauge internals and provides continuous lubrication in the mechanism, all adding up to extended service life. Liquid filling provides greater protection of the gauge internals from corrosive atmospheres. Gauges can be filled with a variety of fluids including glycerin, mineral oil and silicone oil.

2 1/2" PGM Vacuum GaugeGauge delivered on time. On arrival our calibration staff checked the gauge and found that it couldn't be zeroed. Contacted customer service and was told the gauge could not be returned because it had been used. Understood that it was a cheaper gauge could not be calibrated. Was hoping that accuracy could be verified but it failed.
