A custom designed, high accuracy gauge, specifically made to meet the exacting demands of the shooting enthusiast. Custom Dials, with 10 BAR graduations Green flash @ 200 BAR and an impressive accuracy class of 1.6% these are perfect as a replacement part or quality upgrade. These gauges are HPG (High Pressure Gas) safety pattern, which means that they are designed specifically for our application and a requirement when using on gases above 20 BAR. They are unlike many Glycerine filled units that although show 0-5000psi, are designed for fluids, and are not suitable for use with HPG (High Pressure Gas). We recommend that gauges are only fitted by a competent person. Accuracy is +/- 1.6%, which is very high for gauges of this type. They have a robust all Steel Case, with a pressure vent and safety polycarbonate face. There is a built in flow restrictor in case of bourdon tube failure preventing dangerous high speed venting.
