It's the pits.

Digital pit depth gauges from Exacto Machine & Tool are the answer. The gauges are designed for easy use, accuracy, and repeatability. Now available with a choice of bridging bars for different applications:

• PGD-1200: 12" bridge with digital gauge
• PGD-1800: 18" bridge with digital gauge
• PGMB: 4" bridge "Micro Bar"
• PGMBD: 4" bridge "Micro Bar" with digital gauge
• PG1200SB: 12" Step Bar

Corrosion profiles can be plotted quickly and accurately by moving the probe and indicator along the bridging bar. Notched feet prevent the bridge from rocking on a rounded surface. Ceramic magnets securely hold the gauge in place -- a definite bonus when working upside-down. The left-handed scale measures increasing depth as the tip drops into the pit. A locking adjustment screw allows instant calibration to a reference surface. Thumbscrews facilitate one-handed operation.
