The Tri-Gauge® is today’s most versatile Lever Pit Gauge with its Metric and dual Imperial Scales.
Tri-Gauge® serves as a basic Weld Inspection Gauge for; Undercut Depth, Weld Crown Height, a Porosity (diameter) Comparitor; and both Metric and Imperial Rules.
The method of taking a measurement is different:
1) Measuring Corrosion (Depth)
2) Measuring Weld Reinforcement (Height)
3) Mesuring Weld Undercut (Depth)
4) Zero Offset
5) Zeroing the Contact Point
The Tri-Gauge is operator simply lines up the appropriate Pointer with the desired Scale. Specification or Jurisdiction normally governs the selection of the Scale to use.
