Jr. Bridging Pit Gauge® Group
The Jr. Bridging Pit Gauge® Group provides Inspectors with an Economical Alternative to the Bridging Pit Gauge System®. The new Jr. Bridging Pit Gauge® is available as 3 models; the standard Jr. Bridging Pit Gauge®, the Plus, and the Super. The standard Jr. Bridging Pit Gauge® assembles to an overall length of 13½" (340mm). The Jr. Bridging Pit Gauge Plus® can be assembled in either Spanning or Cantilevering Configurations up to 15½" (394mm) long. While the Jr. Bridging Pit Gauge Super® can also be assembled in both Spanning or Cantilevering Configurations, up to 27" (685mm) long.
The Junior's Main Blade, and the optional Extender Blades are fitted with strong magnets that secure any of the Jr. Bridging Pit Gauges® to the surface of the workpiece. These Magnetic Hold Downs have several benefits, such as; Aligning the unit to Concave or Convex surfaces, keeping the operator free to record readings or manipulate the assembly when Scanning through Pits and Weight loss Corrosion. These features position the Plus, and the Super far ahead of any competitive units.

Bridging Pit Gauge® System
The Bridging Pit Gauge® System allows the Corrosion Inspector to Span over or Cantilever into Large Areas of Weight Loss Corrosion, to obtain accurate and consistent measurements, or cross sections, of Pit Depth. As conditions dictate, the operator can simply use the Main Blade or can assemble the Bridging Pit Gauge® up to an over all length of 28½" (725mm).
The contact Surfaces (Blades) of the Bridging Pit Gauge® are fitted with an exclusive Knife Edge, so they can be used on Flat, ID (Convex), and OD (Concave) Surfaces, where a flat or notched contact surface can introduces error on Convex Surfaces. Like our Standard Pit Gauges, the Knife Edge gives the operator a clear view of the contact point, and the area being inspected.
With the addition of the optional Magnetic Hold Downs, the operator uses their width to quickly align the Bridging Pit Gauge® 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 been assembled with a slight contour on an irregular surface.
