Precision Low Pressure Generator PSI-PLPG1

When calibrating low pressure metering instruments including Magnehelic pressure gauges and pressure calibrators, it is essential that a stable pressure source of generating requisite pressure is available at hand. Calibration of pressure measuring instruments for low and very low pressures hitherto presented a challenge because of non- availability of low pressure generators. Polltech proudly presents its model PSI-PLPG1, a precision Low Pressure Generator.

PLPG1 is manually operated and require no electrical power making them useful for testing of Magnehelic Gauges, Pressure Transmitters etc. even when power is unavailable.

Available Model : PSI-PLPG1
