What are the common problems of paint thickness gauge? How to solve it?

A paint thickness gauge is an application of a film thickness gauge that is specifically used to measure the thickness of a coating or paint on a metal surface. It helps the user to accurately measure the thickness of the coating, thus ensuring the quality and consistency of the coating and preventing problems such as over-coating or under-coating.

Paint thickness gauges typically employ non-destructive testing methods that allow the thickness of the coating to be measured without damaging or damaging it. It are usually based on the working principle of magnetic induction or electromagnetic induction technology, probe placed in the coating material on the surface, produce a magnetic field or electromagnetic fields, and then measure the response signal to determine the thickness of coating. Measurements are usually presented in micrometers (μm) or millimeters (mm).

Paint thickness gauge is widely used in paint, ship, automobile, steel, chemical and other fields. It can be used to detect the thickness of paint or anti-corrosion coating on metal surfaces such as car bodies, ships and buildings, so as to ensure its anti-corrosion and anti-rust performance, and can also be used to detect the coating thickness of industrial products.

The measurement results are not accurate.

Instrument readings is not stable.

The instrument is out of order.

The solution
Inaccurate measurements processing: inspection equipment calibration and calibration, whether to need to recalibrate or calibration; Check the preparation of the sample surface, such as whether there are oxides or impurities, etc. Check whether the probe and measuring method of the instrument are correct, select the appropriate probe and measuring method; Ensure that the temperature and humidity conditions of the instrument meet the requirements.

Instrument reading instability treatment: check the environmental conditions of the instrument reading, such as whether there are interference sources, whether there are radiation sources, etc., should be away from the interference sources; Check whether the instrument probe and measurement method are correct, adjust the probe and measurement method to improve the measurement accuracy; Check the power supply of the instrument to ensure that the power supply is stable.

Instrument failure treatment: check whether the instrument has appearance damage or component damage, such as whether there is a loose connector or probe damage; Check the power supply of the instrument, whether there is a power problem; Check whether there is any damage to the internal components of the instrument. If parts need to be replaced or repaired, contact professionals in time for handling.

In addition to the above processing, but also need to pay attention to the following points:

Before using the paint thickness gauge, read the operation manual carefully to understand the use of the instrument and precautions.

During the measurement, ensure that the sample surface is prepared to meet the requirements to avoid affecting the measurement accuracy.

Paint thickness gauge calibration and calibration on a regular basis, to ensure the accuracy of measurement results.

Keep the instrument clean and maintained to avoid dust or dirt affecting the instrument.

ttention should be paid to safety when using the paint thickness gauge to ensure the personal safety of the operator.

In short, paint thickness gauge is a commonly used test instrument, which needs to be paid attention to maintenance and calibration during use to avoid faults and inaccurate measurement results. At the same time, it should be used according to the operation manual and precautions of the instrument to ensure safe and reliable operation.
