Certified Thickness Standards
for Coating Thickness Gages
By DeFelsko

Used to check calibration and operation of coating thickness gages.
Ideal for fulfilling both ISO and in-house quality control requirements.
Supplied with calibration certificate showing traceability to NIST / NPL.

Calibration Standards

Ideal for use in the calibration lab.
Used to verify the accuracy of a magnetic, eddy current or ultrasonic coating thickness gage over its complete thickness measuring range.
Standards with steel or aluminum substrates consist of four (4) standards mounted in a durable leatherette binder (shown at top left).
Plastic thickness standards consist of four (4) polystyrene standards supplied in a rugged acrylic storage box (shown at top right).

Ideal for use with magnetic, eddy current and ultrasonic coating thickness gages

Check Standards

Ideal for use in the field or on the factory floor.
Each set consists of three (3) test standards; one zero (uncoated) and two (2) epoxy coated at high and low thicknesses.
Available with either a ferrous substrate for use with magnetic type coating thickness gages, or a non-ferrous substrate for use with eddy current type gages.
Mounted in durable leatherette binder.
