LS220H Dry Film Thickness Gauge
High accuracy and good stability
Measure coating on ferrous/non-ferrous substrates
Dry film thickness measurement range: 0-2000μm
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.

1. The difference between LS220H and LS221
The functions and parameters of LS220H and LS221 are exactly the same, but the LS220H coating thickness gauge adopts an integrated design and can be operated with one hand; while the LS221 adopts a split design, the probe size is smaller, which is suitable for measuring narrow spaces and some special positions.
