1701 coating thickness gauge instructions_广州市番禺区一思通电子仪器厂

Coating thickness gauge is the use of magnetic induction and eddy current principle of non-destructive testing of metal work on the coating or plating thickness.

The principle of magnetic induction requires that the substrate material of the coating or plating layer is a metal such as iron and steel with good magnetic conductivity and the coating or plating on the surface is a non-magnetic material, and the workpiece and the magnetism are calculated by measuring the magnetic induction intensity of the probe Thickness of the probe coating.

The principle of eddy current is to change the oscillation frequency according to the eddy current effect of the metal substrate. The frequency change is related to the nonmetallic thickness between the substrate and the probe, and the thickness of the nonmetallic coating is calculated.

Buy coating thickness gauge need to know the following points:

The substrate is a magnetically conductive metal (steel, iron) and the coating is a non-magnetically permeable material, with an iron-based coating thickness gauge selected.
The substrate is a non-magnetic metal (copper, aluminum), the coating is a non-metallic material, the choice of non-ferrous coating thickness gauge.
If you have both cases, choose dual coating thickness, the instrument automatically identify the substrate.
The purchase of equipment need to pay attention to the measurement range, the more common coating thickness range of 0 ~ 1250um, if out of range, need special instructions in order to be equipped with the appropriate probe.
The measurement accuracy of the instrument is ± 3%, which requires the user to judge whether the accuracy of the instrument meets the requirements of the production process.
