Used Car Detection|Car Paint Thickness Gauge
A good used car is extremely cost-effective and saves a lot of budget. But buying a used car is also risky and it is difficult for us to judge the past use of the used car and its true condition. As the saying goes, "Be careful to sail the boat for ten thousand years." How can we buy a used car with peace of mind? In addition to experience, it is recommended that you check the real condition of second-hand cars with the help of a testing instrument-car paint thickness gauge !
The car paint thickness gauge uses an electromagnetic induction method to measure the coating thickness. The probe located on the surface of the component generates a closed magnetic circuit. As the distance between the probe and the ferromagnetic material changes, the magnetic circuit will change to varying degrees, causing changes in magnetic resistance and probe coil inductance. Using this principle, the distance between the probe and the ferromagnetic material can be accurately measured, that is, the coating thickness.
Professionals say that the thickness of the painted surface is indistinguishable to the naked eye, but it is certain that as long as the paint or sheet metal is sprayed after leaving the factory, the thickness of the painted surface will be much different from the original paint thickness. Therefore, it is recommended that you use an instrument to measure the paint thickness, that is, a car paint thickness gauge , to check whether sheet metal spraying has occurred. If so, then make sure: Why is the car repainted? Is it to camouflage the useful life of the car? Or disguise those renovated places? If not, congratulations, you can buy this car.
Linshang car paint thickness gauge is the leading inspection instrument in China. It can not only be used to measure non-magnetic coatings on ferromagnetic substrates such as steel, such as varnishes, coatings, enamels, chromium, galvanized, etc. Measurement of non-conductive coatings such as coatings, anodized coatings, or ceramics on non-magnetic metal substrates such as aluminum, copper, die-cast zinc, and brass can also be made. And its measurement method is non-destructive, it neither damages the coating of the tested workpiece nor damages the substrate. Coupled with the instrument's small size, wide measurement range, easy operation, wide application range, relatively low purchase price and fast detection speed, it is a car paint thickness gauge that is worth starting.
Finally, we'll introduce the precautions when measuring: Before measurement, remove the dust, fine debris, grease, corrosion products and other attachments on the contact surface of the test piece, but do not remove any covering material. When measuring, the probe of the car paint thickness gauge should be in vertical contact with the coating of the measurement object. Do not drag the probe, because this will not only cause wear to the probe, but also affect the measurement results.
