Overview
The LS223 Coating thickness gauge is a multifunctional 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 for the measurement of nonconductive coatings (e.g. Coatings, anodic oxidation coatings, ceramics) on nonmagnetic metal substrates such as copper, aluminum, die-cast zinc, brass, etc. The instrument can automatically identify the type of measurement substrate and automatically 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 covering layer on the magnetic metal substrate such as steel can be measured, and the thickness of the nonconductive covering 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
The instrument is based on Hall effect and eddy Current principle for measurement. 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. Measurement mode ("Fe", "NFe" or "Fe/NFe") depending on the type of substrate being tested.
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.
• Ensure that the measured area meets the requirements of minimum measurement surface (φ 25mm) and minimum radius of curvature (convex 5mm, concave 25mm).
• Ensure that the thickness of the substrate meets the requirements of the thinnest substrate (ferromagnetic substrate ≥ 0.2mm, nonmagnetic substrate ≥ 0.05mm).
• Please use the instrument within the working ambient temperature range of 0~ 50 ° C.
• The instrument is powered by 2 1.5V AA alkaline batteries.
