Introduction

The device use both Magnetic Method to measure the non-magnetic coating on a magnetic metal substrate.

Magnetic Method (F-type probe)

When the probe contacts the cover layer, the probe and magnetic substrate forms a closed magnetic circuit; Due to the presence of non-magnetic coating, magnetic resistance changes. The thickness of the cover layer can be derived by measuring the change.

Features

1、Thickness measurement using both Magnetic Method to measure the non-magnetic coating on a magnetic metal substrate and Eddy Current Method to measure the non-conductive coating on a non-magnetic metal substrate.

2、Single-point or two-point method could be used to correct probe system deviation, in order to ensure the accuracy of the device in the process of measuring.

3、Automatic identify ferrous and non-ferrous substrate quickly.

4、 Power voltage indicator.

5、Speaker beep while operating.

6、Power-off automatically when idle; manually power-off available.

7、Negative display function to ensure the accuracy of zero point calibration.

8、 Showing average, max, min value.
