The Baker Hughes/Panametrics 80CAL-TB3 is a 3/16″ calibration fixture engineered to establish precise reference standards for Magna-Mike thickness gauges. This fixture maintains calibration accuracy across the gauge’s operational range by providing a known dimensional reference point for the magnetic probe and target ball measurement system. It enables single-sided access thickness measurement of nonferrous materials—plastics, glass, rubber, ceramics, and composites—where conventional dual-access methods are impractical.
