Overview
The LS223 Coating thickness gauge is a dual-use Coating thickness measuring instrument. It can be used for the measurement of nonmagnetic coatings (e.g. coatings, varnishes, enamels, chromium, galvanized coatings) on ferromagnetic metal substrates such as steel, and nonconductive coatings (e.g. coatings, anodic oxidation coatings, ceramics) on nonmagnetic metal substrates such as copper, aluminum, brass. The instrument can automatically identify the substrate type and switch Measurement mode.
Features
1. No need to calibrate, just zero.
2. Press the button separately, the operation is very simple.
3. Fast measurement, 0.5 seconds to complete a measurement.
4. Ultra-large range test, with a maximum thickness of 5mm.
5. The Abrasion Resistance of the ruby probe guarantees the long-term and effective use of the instrument.
6. Iron aluminum dual-use Probe, automatic identification of measurement matrix, can be quickly and automatically converted.
7. "Fe", "NFe", "Fe/NFe" Measurement mode can be set.
8. The thickness of the nonmagnetic coating layer on the magnetic metal substrate such as steel can be measured, and the thickness of the nonconductive coating layer on the nonmagnetic metal substrate such as copper and aluminum can be measured.
9. Using professional digital Probe technology, digital signal processing is done directly on Probe, Probe is not easily disturbed and provides excellent Test accuracy. Even if the temperature change does not affect the measurement, the reading remains stable to ensure very good Repeatability throughout the measurement process.
Principle
Measurement principles of Hall effect and eddy Current are used. For nonmagnetic coatings on ferromagnetic metal substrates, the magnetic method (Hall effect) is used for measurement; for nonconductive coatings on nonmagnetic metal substrates, the eddy current method is used for measurement.
Applications
Manufacturing, metal processing, chemical industry, commodity inspection
Standards
GB/T4956-2003、GB/T4957-2003、DIN ENISO2808、JJG-818-2005
Steps
1. Select or set the Measurement mode (Fe, NFe or Fe/NFe automatic mode) according to the substrate type.
2. Zero operation on the substrate of the same material without coating.
3. Place Probe vertically on the surface of the coating to be tested for measurement.
Notice
• Zero adjustment is required on the substrate of the same material without coating before measurement.
• Keep the Probe perpendicular to the surface to be measured during measurement.
• The minimum measurement surface diameter is φ 25mm.
• When measuring the curved surface, pay attention to the minimum radius of curvature requirements (convex surface: 5mm; concave surface: 25mm).
• The thickness of the substrate needs to meet the requirements (the thinnest ferromagnetic substrate is 0.2mm, and the thinnest nonmagnetic substrate is 0.05mm).
• Ambient Temperature 0~ 50 ℃, Storage Temperature -20~ 60 ℃.
• Powered by 2 1.5V AA alkaline batteries.
