  1. 1. The difference between LS220 and LS220B car paint meter?

    The Bluetooth automotive paint meter LS220B has mobile phone APP. The instrument can be connected to the mobile phone APP through Bluetooth and record test data, while the conventional automotive paint meter LS220 has this function.

  2. 2. How to judge whether the car has been repainted or not?

    At present, the paint thickness of different brands of cars on the market is not exactly the same. Therefore, when measuring the paint film thickness of a certain car, you can first measure the paint thickness on the car roof, because car roof is rarely affected by external forces and scratches, dents or deformation, it is more likely to retain the original paint thickness.

    To test the specfic position of the car, you can take the upper, lower, left, right, and middle five points to test and calculate the average value of the five data. If the value of one point is greater than the average value of more than 30μm, this position may have been repainted. 

  3. 3. Under what circumstances we need to make zero adjustment?

    When the body material of the car under test changes; the instrument has not been used for a long time; when the ambient temperature changed significantly; after the battery is replaced; when it can not identify the metallic putty and iron galvanized car body.

  4. 4. Can I customize the LOGO and shell of the car paint meter?

    Yes, but there is a minimum order quantity.

    The minimum order quantity for customized LOGO: 100pcs; the minimum order quantity for customized instrument shell: 500pcs.
