I.LS220B Automotive Paint Meter Introduction
LS220B automotive paint meter with Bluetooth is also called car paint meter, which is an integrated instrument with host and probe. The instrument is widely used in the used car industry. When buying a used car, you will encounter a lot of accidental cars that have been repainted or even made sheet metal. It is difficult to judge the overall condition of the car by visual inspection, so most used car appraisers will choose to use a car paint meter with Bluetooth to measure the painted surface thickness of the car.
LS220B automotive paint meter has Bluetooth data transmission function. When testing the painted surface thickness in different places of the used car, the test data can be saved on the mobile phone APP and the test report can be exported. The report can be used to scientifically and objectively analyze the overall condition of the used car painted thickness.

III.LS220B Automotive Paint Meter Characteristics
1.The LS220B automotive paint meter has high-sensitivity probe. Measurement can be completed in 0.5 seconds. 120 sets of data can be saved in one minute.
2.Small size, one button, no need to calibrate. The car paint meter can be used directly after booting.

3.Dual-purpose probe for both iron and aluminum, in the automatic identification (Fe / NFe) mode, the car paint thickness gauge can intelligently identify iron, aluminum, plastic and other measuring substrates. It will automatically switch the substrate after identification.

4. Adopt the advanced digital probe so that the data is stable after testing the same location for mutiple times.
5. With temperature compensation function, it can be used at minus 20 °.
6. No operation within 3 minutes, the instrument will automatically shut down, saving energy and power.
7. Ruby probe has abrasion and corrosion resistance to ensure long service life.
8. The LS220B car paint meter has Bluetooth data transmission function. After successfully connecting with the mobile phone APP, you can record real-time data and view test report, save pictures and share reports through the APP. (Note: APP only supports Android operating system 6.0 and above)

9. "Fe", "NFe", "Fe/NFe" three measurement modes can be set for the LS220B automotive paint meter.

X. FAQ about LS220B Automotive Paint Meter
-
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. 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. 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.
-
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.
