Plastic calibration diaphragms are an economical alternative to coated metal sheets. The accuracy of the calibration specimen was reduced by ±2 μm (±0.08 mil). The coating Thickness Gauge measures when this calibration plate is placed on a smooth metal surface (zero plate).calibrationThickness.
Non-calibrated plastic specimens (foils) provide a quick operational check of the instrument and allow the user to practice measurements while placed on metal. They can be placed on an uncoated metal substrate. However, it is not suitable for use with magnetic pull-out Thickness Gauges.
1)Simulate coatings on specific substrate materials or shapes. According to the requirements of some international test methods, it is convenient to verify the performance of the gage on a regular basis
2) Suitable for all Type 2 electronic coating Thickness Gauges
3) Protect the probe from damage or premature wear when placed on hot or abrasive surfaces
4) Can be placed on top of a soft or adhesive coating film for thickness measurement without the need for a Thickness Gauge probe to depress the coating film
5) Size: 3 x 8 cm
