Pit Gauge

Lever Pit Gauge

Pit Gauge or lever pit guages are the simplest form of Pit Gauges, with an original Patent issued in 1935 as a Pipe Pit Gauge (J.C. Stirling). Until Western Instruments  introduced the Tri-Gauge in 2004, no changes had been made to the original design of Stirling’s. Western’s improved designs make our Pointer Type Pit Gauges effective for Weld Measurement Gauges for Weld Undercut and Weld Reinforcement.
