The Coating Thickness Gauge is widely used in various testing fields, including electroplating, corrosion protection, aerospace, aviation, chemical industry, automotive, shipbuilding, light industry, and commercial inspection. It is suitable for both laboratory and on-site engineering applications. By equipping different probes, it can be adapted to various conditions. This instrument is essential for the non-destructive testing industry.
Main Functions:
- Uses eddy current measurement methods to non-destructively detect the thickness of non-conductive insulating coatings on non-magnetic metal substrates (e.g., rubber, plastic, paint, and oxide films on aluminum, copper, zinc, and tin).
- Fully Chinese menu interface.
- Two working modes.
- Data deletion function.
- Automatic alarm for out-of-limit measurements.
- Low battery indicator.
- Manual and automatic shutdown options.
- Two measurement methods.
- Can store 500 measurement values.
- Limit setting available.
