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.
Select the Standard that most closely matches the measuring range of your gage:
Heavy-duty, waterproof Pelican cases complete with a custom foam insert to securely hold your PosiTest instrument.
