Coating Thickness Gauge Test Ultra-thin Coating Thickness

In the coating thickness gauge industry, the "measurement accuracy" of the instrument has always been a topic that is often talked about. It is also a problem that the majority of coating thickness gauge users are concerned about. What are the factors that affect the measurement accuracy of the coating thickness gauge? How does the high-precision coating thickness gauge produced by Linshang Technology ensures its accuracy?

I. Artificial controllable factors affecting the metal substrate

1. The magnetic properties of the metal substrate

Magnetic induction principles will be affected by the change of testability. In order to avoid the influence of processing technology (the influence of heat treatment and cold processing technology) on magnetism. We generally choose standard films with the same metal properties as the test piece for calibration.

2. Edge effect

The general coating thickness gauge will be sensitive to the sudden change of the metal test piece surface. Therefore, when measuring the coating thickness on the test piece surface, a relatively flat middle part is generally selected. The high-precision coating thickness gauge will reduce the influence of the edge on the measurement accuracy.

3. Curvature

Generally, the curvature of the test piece will have a certain influence on the measurement result. And this effect will be significantly increased with the decrease of the radius of curvature. Therefore, the data measured by the general coating thickness gauge on the curved test piece surface is not reliable.

4. Probe pressure and probe orientation

The pressure of the probe on the test piece will affect the measurement data. During the measurement process, the probe should be kept perpendicular to the surface of the test piece and the pressure is balanced. The high-precision coating thickness gauge will avoid such influencing factors.

II. How does LS225 coating thickness gauge ensure accurate data?

1. The coating thickness gauge adopts advanced digital probe

Linshang new high-precision coating thickness gauge uses advanced digital probe technology to make the measurement data directly on the probe. This will make the probe less susceptible to interference and ensure measurement accuracy.

2. The coating thickness gauge adopts advanced digital oscillation technology

The probe of Linshang new high-precision coating thickness gauge uses digital oscillation technology and high-speed ADC acquisition.

3. Super small probe

The side of the instrument is relatively small, which makes the edge effect and curvature of the above influencing factors relatively small. The small probe is suitable for small workpieces such as nails and bolts.

4. Multi-point calibration

Linshang new high-precision coating thickness gauge uses user multi-point calibration to ensure the measurement accuracy. The coating thickness gauge will correct the curve according to the actual workpiece, making the measurement data more accurate.

5. The coating thickness gauge is equipped with an optional professional fixture

In order to avoid the problem of inaccurate measurement data caused by probe pressure and probe orientation, the new LS225 coating thickness gauge is equipped with a test fixture (optional), which not only makes the measurement more convenient, but also can be brought by human factors.
