The Digital Basic Pit Gauge by Western Instruments is a vital tool in steel inspection when corrosion dictates measurement of pit depth.

For small or curved measurements, the Pocket Pit Gauge is recommended, and to measure across small areas of corrosion or into corners or around welds, risers or reinforcements,
