LS221 Coating Thickness Gauge
Measuring range: 0.0-2000μm
Fast measurement, 0.5s measuring interval
Ferrous/Non ferrous thickness gauge
Seperate thickness meter used in narrow space
LS221 coating thickness gauge is also called coating thickness meter and paint thickness meter. It is a professional instrument for measuring the thickness of metal surface coatings. The host and the probe adopt a separate design, which is convenient for viewing data while testing under complex test conditions. It can be used in the laboratory and engineering field.
There are only four types of ferromagnetic metal elements at room temperature: iron, cobalt, nickel, and gadolinium.
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.

LS221 Coating Thickness Gauge Characteristics
1. The LS221 coating thickness gauge adopt two measurement principles and can identify the substrate automatically. Measurement can be completed in 0.5 seconds.
2. Advanced digital probe technology can keep the zero position stable without drift and frequent zero adjustment.
3. Small size for carrying around.
4. Advanced technology solves the linearity problem of the LS221 coating thickness gauge. No calibration is required just simple zero adjustment to ensure the measurement accuracy.
LS221 coating thickness gauge accuracy test
5. The LS221 digital paint thickness gauge has high sensitivity probe, the test response speed is very high and the data can be measured in 0.5 seconds.
6. With temperature compensation function and digitalizing analog signal function, these sensors are unsusceptible to interference.
7. Wear-proof ruby probe tip for long-term use with strong corrosion and abrasion resistance.
8. The LS221 coating thickness gauge has negative number display function to ensure the accuracy of the zero adjustment and improve the test accuracy.

FAQ
-
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.
