Overview
YONGLIDA QUC-200 Digital Display Magnetic Thickness Gauge is a measuring instrument dedicated to measuring the thickness of nonmagnetic platings on the surface of magnetic materials, with a thickness range of 0 to 200 microns.
Features
1. Adopt magnetic Induction measurement principle to accurately determine nonmagnetic coating thickness.
2. Equipped with a digital display screen, the readings are intuitive and clear.
3. The measurement range covers 0~ 200 microns to meet the requirements of common coating thickness measurement.
4. The error range is controlled within +/- 3%, and the measurement results are reliable.
Principle
The instrument works based on the principle of magnetic Induction. Film thickness of coated platings is calculated precisely by detecting the change of magnetic flux between the magnetic substrate and the nonmagnetic coated platings when the Probe is close to the measured object.
Applications
It is suitable for the measurement of magnetic substrate (such as steel) surface nonmagnetic coatings (such as paints, powder coatings, plastics, enamels, etc.) Film thickness.
Standards
GB/T 1764、GB/T13452.2、ISO2808
Steps
1. Turn it on and ensure that the instrument has sufficient power.
2. Probe in vertical and smooth contact with the coating surface to be tested.
3. Keep the instrument stable and record the measurement after the display reading is stable.
4. If necessary, multiple measurements can be averaged in the same area.
Notice
* Before measurement, ensure that the tested surface is clean, flat, free of oil, rust or impurities.
* The instrument Probe needs to be perpendicular to the measured surface for measurement, and tilt may cause errors.
* Keep the instrument stable during measurement to avoid jitter.
* This instrument is designed for nonmagnetic coating measurement on magnetic substrates, not for nonmagnetic substrates or conductive coatings.
Periodically calibrate the instrument with standard sheets to ensure measurement accuracy.
* Do not use and store the instrument in strong magnetic fields or corrosive environments.
