LS237 car paint meter five advantages

LS237 car paint meter is specialized for car paint thickness inspection. The instrument can not only measure the paint thickness above the ferrous and aluminum materials, identify the non-metallic shell, but also can intelligently identify the ferrous putty and ferrous galvanized layer. LS237 automotive paint meter adopts three-color backlighting as well as three-color indicator display, according to the different paint thickness of the screen and the button displays different color light. LS237 screen is rotatable, facilitating easier reading. LS237 paint film meter also adopts rechargeable lithium battery power supply, ultra-low power consumption. The instrument also has Bluetooth function, equipped with APP, support car inspection report export and sharing.

Intelligent recognition of ferrous putty

In the Fe/Al mode, the instrument can automatically identify ferrous putty, and the measurement is accompanied by two beeps, and both the screen backlight and the button indicator light up red.

Identify car body substrates intelligently

The instrument can quickly detect ferrous, aluminum, galvanized iron and non-metallic car body in Fe/Al mode, which is multi-purpose and easy to identify the car body substrate material.









Three-color display, paint thickness at a glance

The tricolor display can be switched on/off in the settings. The instrument's screen backlight and button indicator lights display three colors corresponding to varying car paint thickness. Paint thickness less than 170μm, white backlight display; paint thickness between 170-350μm, yellow backlight display; paint thickness greater than 350μm or identify ferrous putty, red backlight display.

Equipped with APP, generate vehicle inspection report

With Bluetooth data transmission function, online operation with cell phone APP, which can generate test report and save or share the report.

Ultra-large measuring range, up to 3.5mm thick

The instrument has a large measuring range of up to 3500μm.

Rechargeable lithium battery, ultra-low power consumption

Powered by rechargeable Lithium battery, rechargeable via Type-C interface, ultra-low power consumption, can be used continuously for more than 50 hours after charging once.

Fast measurement speed

The instrument has ultra-fast response speed, 0.5s can complete a measurement.

Ruby probe, hard and wear-resistant

The hard wearing ruby probe reduces measurement errors caused by wear and tear and extends the life of the instrument.

Digital probe, more accurate measurement

Using advanced digital probe technology, digital signal processing is done directly on the probe. The probe is less susceptible to interference and provides excellent test accuracy to ensure very good repeatability.

Three measurement modes can be set: " Fe ", " Al ", " Fe/Al ".

No need for calibration, just zero adjustment.

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

    LS236 and LS233 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”.
