I.LS220H Dry Film Thickness Gauge Introduction
LS220H is an integrated high-precision coating thickness gauge, which combines the Hall effect and eddy current thickness measurement principles. This gauge can be used for coating thickness on various metal substrates.
There are only four types of ferromagnetic metal elements at room temperature: iron, cobalt, nickel, and thorium.
Common non-ferromagnetic metals: copper, aluminum, magnesium, 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.

IV.LS220H Dry film thickness gauge Characteristics
1．The LS220H dry film thickness gauge has simple design and small size. It is easy to carry and operate.
2．0.5S fast measurement, how fast your hand can be how fast the gauge can be.
3．The advanced digital probe is used to keep the zero position stable for a long time without drifting. The test data is stable after testing the same position for multiple times.
4．The accurate measurement data and good repeatability to ensure that it passes the inspection of Chinese national metrological testing.
5．Dual-use probe for both iron and aluminum. The dry film thickness gauge has intelligent identification of measurement substrate and fast automatic transfer.
6．Using temperature compensation technology, the mil gauge can be used at minus 20 degrees Celsius. Ensure measurement accuracy at different temperatures.
7．Ruby probe with abrasion and corrosion resistance to ensure long service life. Avoids errors caused by wear.
8．This coating thickness gauge can be used for coating measurement on ultra-thin substrates: Fe: 0.2mm / NFe: 0.05mm.
9. The LS220H coating thickness gauge has three measurement modes:Fe mode, NFe mode and Fe/NFe mode.

IX. FAQ about LS220H Dry Film Thickness Gauge
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.
