XHM-700 series coating thickness gauge

1、 Overview:

The XHM-700 series coating thickness gauge is the crystallization of high-tech. It adopts single-chip technology, with high accuracy, digital display, stable indication, low power consumption, simple and convenient operation, no calibration knob, single probe full range measurement, small size, and light weight; And it has storage, readout, and low voltage indication, and its performance has reached the advanced level of contemporary international similar instruments.

2、 Application scope:

This instrument adopts magnetic thickness measurement method, which can conveniently and non destructively measure the thickness of non-magnetic coatings on ferromagnetic materials, such as zinc, copper, chromium coatings on steel surfaces or coatings of paint, enamel, fiberglass, spray coating, asphalt, etc. This instrument is widely used in industries such as machinery, automobiles, shipbuilding, petroleum, chemical, electroplating, spraying, enamel, plastics, etc., especially suitable for the anti-corrosion industry.

3、 Working principle:

The XHM-700 series coating thickness gauge uses electromagnetic induction method to measure the thickness of coatings. The probe located on the surface of the component generates a closed magnetic circuit, which will change to varying degrees as the distance between the probe and the ferromagnetic material changes, causing changes in magnetic resistance and probe coil inductance. This principle can be used to accurately measure the distance between the probe and the ferromagnetic material, that is, the thickness of the coating (plating) layer.
