LS233 automotive paint meter is a low-temperature-resistant car paint thickness measuring instrument equipped with two screens. It can be used normally at an ultra-low temperature of -40℃. The dual-screen design can ensure that users can quickly read when measuring cars at any angle. The paint film measuring instrument adopts the dual principles of Hall Effect and eddy current. It is dual-use for both ferrous (iron) and non-ferrous (aluminum) metal substrate. It can automatically identify iron, aluminum and non-metallic substrates. In addition, It can discover metallic putty and iron galvanized car body automatically. It is easy to operate, compact and portable. Using this automotive paint meter, car appraisers can easily solve their problems of car evaluation.

  1. 1. The difference between LS233 and LS236 car paint meter?

    LS233 and LS236 car paint meter both can identify metallic puttty and iron galvanized car body, however LS236 features a three-color backlight display function, LS233 does not. When discovered metallic putty, the screen of LS235 will turn red while turns green recognizing iron galvanized car body.

  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 recognize ferrou putty or iron galvanized cae 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. If you want to know more about the Linshang coating thickness gauge, Please click “Paint Thickness Gauge Selection and FAQ”.
