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.

Resolution: 0.2mm (0.005″)

The Junior Tri-Gauge VM® Lever Type Pit Gauge is today’s most accurate Lever Pit Gauges, with a continuing tradition of Metric and dual Imperial Scales. This Junior Tri-Gauge® serves its traditional use as a Pit Depth Gauge and as a Weld Inspection Gauge for Weld Undercut Depth, Weld Crown Height, and both Metric and Imperial Rules. Like the original Tri-Gauge®, Junior Tri-Gauges is fitted with our Contact Point Offset Correction® for improved accuracy and repeatability. Any Lever Pit Gauge is intended to evaluate corrosion/erosion and not an absolute measuring tool. It comes with a Vinyl Sheath Storage Case and Instructions.
