LS230 is the first car paint meter in the ultra-low temperature environment of -40 ℃. This car paint meter uses a low temperature resistant OLED liquid crystal display. The LS230 car paint meter is professionally used for the detection of the paint film thickness of used cars. It adopts the two measuring principles of magnetic induction and eddy current, which can quickly measure the paint film thickness on metal substrates such as steel plates and aluminum alloys. It can also identify non-metallic substrate.
