The Junior Tri-Gauge is today’s most accurate Lever Pit Gauge with a continuing tradition of Metric and Dual Imperial Scales.

The Junior Tri-Gauge serves its traditional use as a Pit Depth Gauge, but also as a Weld Inspection Gauge for: Weld Undercut Depth, Weld Crown Height, and both Metric and Imperial Rules.

The method of taking a measurement is different:

1) Measuring Corrosion (Depth)

2) Offset Correction

3) Measuring Weld Reinforcement (Height)

4) Mesuring Weld Undercut (Depth)

5) Zero Offset

6) Zeroing the Contact Point

The Operator simply lines up the appropriate Pointer with the desired Scale; fractions of an inch (1/64”), millimeters (0.2mm), or thousands of an inch (0.005”).
