substrate generate vortices, the feedback effect of the vortex on the probe and the thickness of the cladding forms a corresponding relationship, and the purpose of measuring the thickness of the cladding is achieved by checking the amount of this feedback.
Measurable Objects: Used to measure the thickness of plating or coating on metal surfaces. Specifically, it can measure the thickness of the non-magnetic coating layer on the surface of magnetic materials such as steel/iron, and also the thickness of the coating on the surface of non-magnetic materials such as copper/aluminum. Maximum 1500um coating thickness test, minimum 0.1um resolution.
Multi-functional Design: It supports auto-calibration, beeping reminder, data storage, and automatic shutdown functions.
Rechargeable Battery: Built-in 3.7V 400mA lithium battery, USB direct charging, with long endurance and long service lifespan.
Wide Applications: It is widely used in automotive ink inspection, electroplating layer, surface process, pipeline anti-corrosion layer, surface mechanical equipment anti-corrosion, chemical equipment, quality control and other fields.
