The test pressure gauge can be used to check common pressure gauge which is using in the industry process with high precision measuring.
A type test pressure gauge can work perfectly in the occasion without corrosion to copper alloy.
B type can work in varies corrosion environments to do high precision measurement in the corrupt mediums.
This series includes bottom/back mounting and bottom/back with flange mounting.
