Thickness Tester

Leeb 252 Coating Thickness Gauge – Doryang

Product description: Leeb 252 Coating Thickness Gauge offers precise measurement of non-magnetic and non-conductive coatings on metal surfaces, ideal for industrial applications.
INQUIRY

Utilizes both magnetic induction and eddy current measurement methods.
Enables non-destructive testing of:
- Non-magnetic coatings (such as aluminum, chromium, copper, zinc, tin, rubber, and paint) on magnetic metal substrates (such as steel alloys and hard magnetic steel).
- Non-conductive insulating coatings (such as rubber, plastic, paint, and oxide films) on non-magnetic metal substrates (such as aluminum, copper, zinc, and tin).
One-button operation for ease of use.
Compact and integrated design, making it more portable.
