Double-layer Film Thickness Gauge selection case

client needs

1. The test substrate is iron or aluminum, the coating is zinc, paint coating

2. I want to choose a coating Thickness Gauge that can not only measure the film thickness separately, but also measure the total film thickness. You can adjust the mode. If you want to measure the double layer, it will display the double layer, and the total thickness will display the total thickness.

case analysis

The first point: determine the appropriate thickness measurement method

The customer's substrate is iron or aluminum, which is ferrous metal or non-ferrous metal. It is necessary to choose a Thickness Gauge with both magnetic induction and eddy current thickness measurement methods.

The second key point: determine the specific type of Thickness Gauge

The customer wants to measure the thickness of the composite coating on the metal substrate, and requires that the thickness of the two coatings and the thickness of the total coating can be measured separately. At present, the domestic Thickness Gauge that can test the thickness of the paint layer and zinc layer in the composite coating system is PosiTector 6000 FNDS from Defelsko in the United States, which is a composite coating Thickness Gauge.

This Thickness Gauge can choose composite measurement mode and non-compound measurement mode. When it is in composite measurement mode, it can calculate the thickness of paint layer and zinc layer separately; Measure the total thickness of different coatings.

The measurement parameters of PosiTector 6000 FNDS coating Thickness Gauge are as follows:
