How to measure the zinc coating thickness  on a steel wire of 3mm diameter

Obsnap product specialist used an Elektrophysik Coating Thickness Gauge model: MiniTest 735 F05M-90. Firstly, we calibrate the coating Thickness Gauge MiniTest 735 F05M-90 by performing zeroing on the uncoated 3mm steel wire, and then followed by  calibrate on 1^st and 2^nd thickness standards. We then store the calibration setting into the Batch memory for easy and accurate measurement whenever we need to measure on this 3mm diameter wire.
The gauge was then ready to take coating thickness measurement precisely to 0.75% accuracy. As you can see, the zinc coating thickness measurement on steel wire were at 32.55 and 33.05 microns.
