DeFelsko STDZALMM Zero Plates Medium Square, Diameter: 100 mm x 100 mm x 6 mm (4" x 4" x 0.25"), Aluminum, for use with the PosiTector 6000 FNTS, NKS probes

The DeFelsko STDZALMM Zero Plates Medium Square, Diameter: 100 mm x 100 mm x 6 mm (4" x 4" x 0.25"), Aluminum, for use with the PosiTector 6000 FNTS, NKS probes is used to provide a substrate where none exists. Large sheets of material such as paper, plastic, fabric and rubber can be measured with a coating thickness gage by placing the material over the zero plate. This is useful when the measured item is too large to access with a micrometer or other device. For example the screen printing industry uses zero plates to measure the thickness of the "substrate" being printed.
