LS232 is the first dual-screen OLED car paint meter that resist ultra-low temperature on the market. This car paint meter is professionally used for the detection of paint film thickness of second-hand cars. It adopts two measuring principles of Hall Effect and eddy current. It can quickly measure the paint thickness on non-magnetic metal substrates such as aluminum and paint thickness on magnetic substrate such as steel. The car paint meter uses a low-temperature resistant OLED dual-screen display, which can be used normally in low temperature environment of -40℃. The meter can display the data normally. Used car inspectors can use this paint thickness meter to quickly find out where the paint has been repaired by measuring the paint thickness on various parts of the car.
