Automotive paint meter

In the detection of the automotive paint meter LS220, the car roof is generally used as a reference. If the value of other parts is significantly higher than the reference value, the part of the vehicle can be judged that it has been repaired by sheet metal and spray paint. In the second-hand car identification process, if the inspector finds that the difference between the value and the reference value is very large, it will further check whether the vehicle has traces of accidents there and determine whether it is an accident.
Generally, the thickness of most cars is between 80-140, and a small number of imported cars may reach more than 150. If you test the left door of the car, you can take the five points of the door up, down, left, right, and the middle to test five points. The value you want to add and divide by 5 is the average value. If the value of a point is greater than the average value of 30um or more, the car may be repaired. If you completely replace the car door, you need to check from the internal screw and other joints. If a used car belongs to an accident, then there must be traces of sheet metal or paint repair on the painted surface of the body, and the repair range will be relatively large. Therefore, as long as it involves the detection of second-hand accident vehicles, it is essential to do paint inspection projects. In this way, the historical situation of major and minor accidents that occurred in the vehicle can be revealed, and whether the vehicle belongs to the accident vehicle can be judged. It can be said that after reading the paint surface of the vehicle, you can roughly understand the scratching and accident history of the vehicle. Of course, if you want to completely determine whether the vehicle is a technically recognized accident car, you still need the equipment of the second-hand car appraisal appraisal through the *** equipment to integrate the chassis, front and rear anti-collision beams, body structure and other items. The test result shall prevail.
If you only check the paint surface of the car body, you can use the second-hand car identification artifact-"paint film instrument" is an instrument that detects the thickness of the car paint surface to determine whether the car has signs of sheet metal or spray paint.
