Dor Yang 251 Coating Thickness Gauge

The Dor Yang 251 Coating Thickness Gauge is an integrated eddy current portable coating thickness gauge. It enables fast, non-destructive, and precise measurement of coating and plating thickness. It is suitable for both laboratory and on-site engineering applications.
Widely used in manufacturing, metal processing, chemical industries, and commercial inspection, it is a professional instrument for material protection.

Functions & Features

The Dor Yang 251 adopts the eddy current principle for thickness measurement. It can non-destructively measure the thickness of non-conductive coatings (such as rubber, paint, and anodized films) on non-magnetic metal substrates (such as copper, aluminum, zinc, and tin).

It features an automatic shutdown function.
