The device uses magnetic thickness measurement method, which non-destructively measures thickness of non-magnetic coating (such as: aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal substrates (such as steel, iron, alloy and hard magnetic steel, etc.).
a.Magnetic Method (F-type probe)
When the probe contacts the cover layer, the probe and magnetic substrate forms a closed magnetic circuit; Due to the presence of non-magnetic coating, magnetic resistance changes. The thickness of the cover layer can be derived by measuring the change.
b.Features:
1. Portable design, palm-sized
2. High-speed DSP chip with fast measurement capability
3. In the dual probe automatic identification of iron-based and non-ferrous materials, without manual conversion
4. Two calibration methods, and the two point zero calibration standards
5. Wide angle LCD display
6. Converting metric and imperial units
7. Has the power under voltage tips
8. During operation beep alerts
9. With automatic shutdown
