How to Choose Suitable Coating Thickness Gauge?

I. Coating Thickness Gauge Application (Non destructive testing)

Linshang coating thickness gauge can measure non-magnetic coatings on various magnetic metal substrates (such as steel, iron, etc.) and non-conductive coatings on non-magnetic metal substrates (such as aluminum, copper, zinc, etc.) . It is dual use coating thickness measurement device that use both eddy current and magnetic measuring principle. We provide various coating thickness gauges for the customers based on their industry. If you want to find select the best coating thickness gauge in 2020. Please read the coating thickness measurement information we shared below.

1. Automotive paint meter in car industry

The car surface paint thickness is measured by an automotive paint meter to determine whether the car has been repainted, sheet metal or other repairs. The car is evaluated based on this. The repair position of the used car can be quickly found by using automotive paint meter. Place the car paint meter vertically on the car paint surface, the paint thickness of this position is displayed on the screen immediately. With scientific measured data, the condition of the used car is more intuitive.

2. Coating thickness gauge use in other industries (especially surface treatment industry)

Thickness of anti-corrosion, fire-proof, anti-corrosion, anti-wear, thermal insulation coatings and other materials can be measured by coating thickness gauge, such as paint, coating, ink, anodized layer, electroplated layer, thermal spray coating, etc. Different models of Linshang coating thickness gauges are used in different industries. Some of the examples are listed below:

3. Thickness testing of other materials based on metal

Materials such as film, glass, plastic, rubber, ceramics, enamel can be measured by Linshang coating thickness gauge. (perform zero adjustment with provided zero adjustment plates and test thickness of other non-magnetic metal materials).

II. How to Select Automotive Paint Meter for Car Industry?

We have four models of automotive paint meters: standard type LS220, Bluetooth automotive paint meter LS220B and two low temperature resistant types: single OLED automotive paint meter LS230 and dual OLED automotive paint meter LS232. The measurement range, measurement accuracy, resolution and other main parameters of these four car paint meters are all the same.  But they have a little difference. If you have special requirements such as Bluetooth function and low temperature resistant ,please read the following information carefully:

1. No special requirements

Please directly choose LS220 automotive paint meter

2. Store measurement data or Bluetooth

Please choose LS220B Bluetooth automotive paint meter

LS220B automotive paint meter can transmit test data to mobile phones via Bluetooth. Users can record and view multiple sets of test data on the mobile phone APP. It can generate and analyze automotive paint film thickness test reports.

3. Use in low temperature environment

Please choose LS230 single OLED automotive paint meter or LS232 dual OLED automotive paint meter

LS230 automotive paint meter has low-temperature resistant OLED, which can work normally in the temperature range of -40℃-50℃. There will be no failure of data display at low temperatures.

LS232 automotive paint meter has two displays respectively on the top and front. For the other functions and parameters, it is the same as LS230.

III. How to Choose Coating Thickness Gauge in other Industries?

If you need to select a coating thickness gauge used in other coating industries, then you can choose LS220H, LS221, LS223 and LS225 four coating thickness gauges. Please follow the prompts below to select a suitable coating thickness gauge.

1. Built-in sensor or an external sensor probe?

  • The LS220H coating thickness gauge has integrated probe, which can be operated with one hand. The operation is relatively simple.

  • The LS221, LS223 and LS225 coating thickness gauges have external probes. The probes of these three coating thickness gauges are connected to the host through a line. The probe is very small and can be placed in a narrow space or used when the measured position is higher or lower. We can use another hand to hold the gauge, so we can easily read the data.

2. Ultra-small size or irregual shaped workpiece? 

  • If you want to measure a metal material with a special shape or a small size and a large arc, please choose the LS225 coating thickness gauge.  LS225 plating thickness tester has two probes: F500 and N1500.

    LS225+F500 plating thickness tester is used to measure the coating thickness on ferrous metal substrates. Its coating thickness measuring range is 0.0-500μm. 

    LS225+N1500 plating thickness tester is used to measure the coating thickness on non-ferrous metal substrates. Its coating thickness measuring range is 0.0-1500μm. 

  • If the diameter of the material you measure is greater than 25 mm and there is no obvious arc, please choose LS220H, LS221 and LS223 coating thickness gauges.

3. Large thickness, ordinary coating thickness or ultra-thin coating?

  • If you want to measure the thickness of ultra-thin plating layer (<500μm), please choose LS225 plating thickness gauge. 

  • If you want to measure the coating thickness within 2000μm (2mm), please choose LS220H or LS221 coating thickness gauges.

  • If you want to measure the thick coating thickness, please choose LS223 coating thickness gauge. 
    The coating thickness measurement range of F5N3 is 0-5000μm (magnetic metal substrate), 0-3000μm (non-magnetic metal substrate)

IV. FAQ about Coating Thickness Gauge

1. What is the car paint film thickness?

The car paint film thickness is not an absolute value. The original car paint thickness of different brands  is not exactly the same. Even the paint film thickness at different locations on the same car is slightly different.

The paint film thickness on the roof of some cars may be only about 80μm, while the paint film thickness in other places may be 120μm. When measuring the paint film thickness of the car, the most important thing is to detect the uniformity of the paint film thickness at each position. When measuring a car of an unfamiliar model, if the original paint thickness cannot be determined, the car roof paint film thickness can be used as a reference to compare the thickness of other locations. Because the roof location is not prone to scratches or impact, other paint film thickness at the location is slightly higher than the paint film thickness on the car roof. The user can find experience from multiple measurements. However, if 100 μm is measured on the roof and 300 μm is measured elsewhere, then the thicker area is likely to be repainted or scratched.

2. What is the measuring principle of coating thickness gauge? What do "Fe" and "NFe" stand for?

  • Linshang coating thickness gauge (except LS225 plating thickness gauge) adopts magnetic induction and eddy current principle.

  • The coating thickness gauge can automatically recognize "Fe (ferrous)" and "NFe (non- ferrous)" two different metal substrates. It is recommended to use the "Fe (ferrous)" mode for measuring magnetic metal substrates (such as steel, iron) and the "NFe (non- ferrous)" mode for measuring non-magnetic metal substrates (such as aluminum, copper). For the substrate type, you can also select the "Auto" mode. The coating thickness gauge can automatically recognize the substrate type and switch the measurement mode.

3. What is the response speed of Linshang coating thickness gauge?

Linshang coating thickness gauge response speed is very fast compared with other coating thickness gauges on the market. It uses a highly sensitive probe, measurement can be completed in 0.5s. 

4. What are "mil" and "μm"? How to convert the coating thickness gauge unit?

  • The terms "mil" and "micron" are units of thickness measurement.

  • In the English system, 1 mil = 0.001 inch

  • In the metric system, "1 μm" means a micron, 1 μm = 0.001 mm

  • To convert Mils to Microns: 1 mil = 25.4 μm
