DeFelsko Certified S4 Standards

DeFelsko’s Certified Coating Metal Plates for verifying the accuracy and operation of ferrous coating thickness gauges.

SKU: DEF-STDS4 Category: Tags: ,


DeFelsko’s Certified Coated Metal Plates are ideal for the PosiTector 6000 FXS*.

For when verification of gauge accuracy at a test site is required each time a coating thickness gauge is put into service, DeFelsko’s certified coating thickness standards have measured values traceable to a National Metrology Institution.

These standards are used to verify the accuracy and operation of mechanical, electronic, eddy-current, or ultrasonic coating thickness gauges, and are certified and labelled in both Metric and Imperial units.

The S4 Standard features a range of 0 to 1900 µm (75 mils).

Certified Coated Metal Plates for ferrous probes have an accuracy of ± 0.43 µm ± 0.017 mil.

*PosiTector FXS probes with a range of 0-1500 µm (0-60 mils) and Serial Numbers <361485 should use the S1 Standard


All certified standards are supplied with a Certificate of Calibration traceable to NIST or PTB.
