Pneumatic Comparator Regulator - Pressure Calibration Using Bottled Gas

Pneumatic comparator regulator for the calibration of pressure gauges or pressure transmitters using bottled gas or air (we suggest Nitrogen) to a maximum pressure of 120 bar. The regulator features 2 ports, one for the gauge on test and the other for the master test equipment such as a test gauge, precision transmitter or digital calibrator. The unit incorporates two fine metering valves for the precise control of rising and falling pressure.

This comparitor will also require a master reference instrument to be used, we suggest either a master test gauge, digital test gauge or precision pressure transmitter depending on the accuracy of the instruments under test.
