Coating thickness gauge for used car

In the past, when testing vehicles, without the help of coating thickness gauges, it was undoubtedly a major problem to detect the thickness of the body paint. It also played a great role in identifying whether it was a used car, and formed a protection and decoration on the body surface. The coatings, such as coatings, coatings, claddings, coatings, and chemically generated films, are called claddings in relevant national and international standards. The measurement of cladding thickness has become an important part of vehicle quality inspection, and it is also an excellent product. The necessary means of quality standards.


In the process of internationalization, China's export vehicles have clear requirements for the thickness of the cladding. Due to the characteristics of small accuracy and error, high reliability, high stability and easy operation in the measurement process of the coating thickness gauge, the coating thickness gauge plays an important role in controlling and ensuring product quality, which is necessary for vehicle inspection Essential measuring instruments.


First, the factors that affect the accuracy of the coating thickness gauge test results

1. The effect of whether the film thickness correction sheet is qualified on the test result


As the measurement standard of the coating thickness gauge, the film thickness correction sheet needs to be inspected by the technical supervision department and attached with the inspection report. However, it is not common among instruments at home and abroad. It is precisely because of this that the instrument measures Accuracy and reliability are affected by whether the film thickness correction sheet passes the qualified test.


2. The influence of the degree of probe wear on the test results

When the coating thickness gauge is used to detect the thickness of the vehicle coating, the probe inevitably contacts the vehicle shell, so the most susceptible part of the thickness gauge is the probe. The life of a thickness gauge probe It also determines the use of the thickness gauge.


3. Whether the detected substrate exceeds the detection range of the instrument has an influence on the detection result

The instrument belongs to the standard measurement range for the detected vehicle materials. If the substrate measured during the detection is not within the detection range of the thickness gauge, the results displayed by the instrument will lack accuracy.
