LS220H Dry Film Thickness Gauge
1. Measuring range: 0.0-5000μm
2. High-quality digital probe ensures accurate measurement and stable data
3. Dual use on ferrous/non-ferrous substrates, Identify substrate automatically
Description
LS220H coating thickness gauge four major advantages
LS220H is an integrated high-precision coating thickness gauge, which combines the Hall effect and Eddy current thickness measurement principles. Based on the Hall effect, the instrument can measure non-ferromagnetic coatings on ferromagnetic metal substrates, while under the Eddy current principle effect, it can measure non-conductive coatings on non-magnetic metal substrates.
- There are only four types of ferromagnetic metal elements at room temperature: iron, cobalt, nickel, and gadolinium.
- Common non-ferromagnetic metals: copper, aluminum, zinc, chromium, etc.
- Hall effect: can be used for the measurement of non-ferromagnetic coatings on ferromagnetic metal substrates.
- Eddy current: can be used for the measurement of non-conductive coatings on non-magnetic metal substrates.
