Products Description
This is a non-destructive testing instrument that uses the principle of magnetic induction to measure the thickness of non-magnetic coatings on the surface of ferromagnetic metals.
Magnetic coating thickness gauge
Model:LJLMM-1
I. Product Introduction
The magnetic coating thickness gauge is a non-destructive testing instrument used to measure the thickness of non-magnetic coatings on magnetic metal substrates (such as steel and iron). It is widely used in manufacturing, coating, quality control and other fields.
II. Standards
ISO 2178 — Measurement of coating thickness — Magnetic method
ASTM B499 — Standard Test Method for Measurement of Coating Thicknesses by the Magnetic Method
III. Main Functions:
An instrument that uses magnetic measurement methods to non-destructively test the thickness of coatings on magnetic metal substrates(such as aluminum,chromium,copper,zinc,tin,rubber,paint,etc.on steel alloys and hard magnetic steel).
