Polystyrene blocks are ideal for verifying the accuracy and operation of coating thickness gauges and are an important component in fulfilling both ISO and in-house quality control requirements. Polystyrene thickness standards consist of 4 blocks supplied in a rugged acrylic storage box Many organizations require verification of gauge 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 from the chart below the Standard that most closely matches the measuring range of your gauge

  • Accuracy: ± (2.5 µm + 0.05% of thickness) ± (0.1 mil + 0.05% of thickness)
  • 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
  • Individually serialized for traceability to NIST or PTB - includes a Certificate of Calibration
  • Certified and labeled in both Metric and Imperial units
