Calibration Substrates & Thickness Foils

All PD8's are supplied ready to use out of the box. We supply each PD8 with two
uncoated metal check-pieces (Steel for Fe & Aluminium for NFe). These enable users to
simply re-calibrate the gauge back to factory settings at anytime. In addition we ship 4
thickness foils with each gauge so it can be checked for accuracy throughout the
thickness range in both Ferrous and Non-Ferrous modes at anytime for peace of mind.
