Certified Polystyrene Blocks

Certified Polystyrene Blocks are for use with gages that measure over 1500 µm (60 mils).

They have an accuracy of:

+(2.5 µm + 0.05% of thickness)+(0.1 mil + 0.05% of thickness)

Certified Coated Metal Plates & Polystyrene Blocks

Certified coated metal plates and polystyrene blocks are ideal for verifying the accuracy and operation of coating thickness gages and are an important component in fulfilling both ISO and in-house quality control requirements.

Many organizations require verification of gage accuracy at the test site each time a coating thickness gage is put into service and at frequent intervals during use. Ideal for this purpose, DeFelsko certified coating thickness standards have measured values traceable to a National Metrology Institution.

• Used to verify the accuracy and operation of any Type 1 (mechanical) and Type 2 (electronic) magnetic, eddy-current or ultrasonic coating thickness gage
• Ideal for use in the calibration lab, in the field or on the factory floor
• Standards with steel or aluminum substrates consist of 4 plates mounted in a protective binder
• Polystyrene thickness standards consist of 4 blocks supplied in a rugged acrylic storage box
• Individually serialized for traceability to NIST or PTB - includes a Certificate of Calibration
• Certified and labeled in both Metric and Imperial units
