The Tri-Gauge is a versatile Lever Pit Gauge, with its Metric and dual Imperial Scales. Additionally, the Tri-Gauge serves as a basic Weld Inspection Gauge for; Undercut Depth, Weld Crown Height, a Porosity (diameter) Comparator; and both Metric and Imperial Rules.
The Tri-Gauge is fitted with a Patented pointer Offset Correction(bent) for improved accuracy and repeatability. Lever Pit Gauges are intended to evaluate corrosion, and not as an absolute measuring tool.
