As conditionsdictate, the operator can simply use the Main Blade or canassemble the Bridging Pit Gauge® up to an over all length of28½” (725mm). The contact Surfaces (Blades)of the Bridging Pit Gauge® arefitted with an exclusive KnifeEdge, so they can be used onFlat, ID (Convex), and OD(Concave) Surfaces, where aflat or notched contact surfacecan introduces error onConvex Surfaces. Like ourStandard Pit Gauges, theKnife Edge gives the operatora clear view of the contactpoint, and the area being inspected. With the addition of the Magnetic Hold Downs, the operator uses their width to quickly align the Bridging PitGauge System® to a curved surface. This leaves his hands free to scan through very large areas of weight loss corrosion.This holds true when the Bridge Elements have beenassembled with a slight contour on an irregular surface.
