LINSHANG - LS221 Coating Thickness Gauge (Fe & NFe)
| Previous | 14 / 66 | Next |
LINSHANG - Coating Thickness Gauge
Brand: Linshang
Model: LS221
* (Fe & NFe Combination Probe)
Features:
* Accuracy: +/-(3%+2um)
* Suitable for coating thickness which higher than 20micron.
Product Introduction:
The LS221 Coating Thickness Gauge is a specialist instrument for measuring the thickness of coatings on metal surfaces. The instrument combines the Hall effect and Eddy current principles to measure the thickness of non-ferromagnetic coatings on ferromagnetic metal substrates and the thickness of non-conductive coatings on non-magnetic metal substrates. The host and probe of LS221 is separate, which makes it easy for the user to view the data under complex testing conditions. It can be used in the laboratory and engineering field.

- 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.
- 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.
