PVX-B (basic)

PVX-B Precision Gauge
PVX-B (basic) is a digital precision thickness gauge that offers a number of features, transducer options, and a large alpha-numeric data logger to provide versatility for a number of application scenarios. The high speed scan feature speeds up the inspection process by taking 32 measurements per second and reporting the minimum reading scanned when the transducer has been removed from the test material. The visual and audible alarm with hi and lo limit settings for specific application tolerances. The time based B-Scan feature provides a cross section view of the opposite material surface. PVX-B comes complete with our Windows® PC software for transferring data to and from a PC.
