The WESTport Air Gage Amplifier converts back-pressure changes from any air plug, ring, snap, spindle or probe into a high-magnification dial reading. Zero and span adjust from the front panel, so one unit serves multiple gaging setups.

• Analog dial readout graduated in .0001″ for fast in-tolerance checks
• Works with WESTport air plugs, rings, snaps, spindles and probes
• Set against certified master setting gages; regulated clean, dry air supply (20 PSI max)
