InstruMate low pressure gauge model 122AB alongside with 122AA are the strongest design for a low pressure gauge with brass connection. The case in this capsule pressure gauge is Outside Bayonet (openable) which makes it easy to recalibrate and adjust the pressure gauge if needed. Outside bayonet bezel provides you with the advantage of a little bigger dial face within the same nominal size, thus easier reading.Choosing reliable capsule measuring system assures you can rely on it for any low pressure monitoring with medias not attacking copper alloys.

All InstruMate pressure gauges have geometrically balanced dial designs to make gauge readings easier


  • Low pressure/vacuum measurement of gas and dry air
