Portable Automotive Paint Coating Thickness Gauge

The portable automotive paint coating thickness gauge can obtain the thickness and uniformity of the car paint film by measuring multiple positions on the car surface. Through the comparison of the paint film thickness data at multiple locations, we can find which parts of the car have been scratched. This feature is very effective when evaluating used cars.

At present, there are many brands of portable automotive paint coating thickness gauges, such as the German Q-Nix, the British Elcometer, Linshang, TQC, DeFelsko, Extech and so on. Below we will introduce the popular products of the three automotive paint coating thickness gauge brands from various aspects. The three popular products are the Linshang LS220, the Q-Nix 4500 series from the German Q-Nix and the Elcometer 456 series from the UK.

1.Principle of automotive paint coating thickness gauge 

The three automotive paint coating thickness gauges use two measurement principles, magnetic thickness measurement and eddy current thickness measurement. The dual principle enables the three instruments to measure the coating thickness on magnetic metal substrates and non-magnetic metal substrates. 

2.How does a thickness gauge work?

The Linshang LS220 automotive paint coating thickness gauge and the Q-Nix 4500 do not need to be calibrated after starting up, only need to make zero adjustment on the uncoated substrate (iron and aluminum plates equipped with the instrument).

The Elcometer 456 automotive paint coating thickness gauge needs to be calibrated and perform zero adjustment before use. Calibration requires a standard board of known thickness to ensure that the instrument's data meets the requirements. If the data does not match, the data can be manually calibrated to this thickness. It is also necessary to use an uncoated work piece for zero adjustment.

The three automotive paint coating thickness gauges are bilingual in both Chinese and English. Users can set them to the appropriate language before testing according to their needs. Both of them can automatically identify the measurement substrate. After setting all the parameters, the coating thickness on different substrates can be measured at any time and the type of the substrate can be quickly identified to realize mode switching.|

3.Value-added function of the automotive paint coating thickness gauge

Both Linshang LS220B and Elcometer 456 automotive paint coating thickness gauges have Bluetooth data transmission function, which can bind the instrument to the mobile APP and record test data to generate test reports.

The Q-Nix 4500 and Elcometer 456 automotive paint thickness gauges are available in a variety of ranges, allowing the user to select the appropriate measurement range for the tested coating thickness.

The Elcometer 456 has a unique data scanning function that allows multiple test data to be acquired by moving the test probe in a short time and exported via a USB interface.

4.Coating thickness gauge price

According to the different range size and the presence or absence of Bluetooth and USB data transmission, we have arranged the above coating thickness gauge prices (prices from the network, for reference only, the actual price is subject to the official website price).

1. Linshang LS220 (2mm, no Bluetooth data transmission function): 790RMB, about $118

2. Linshang LS220B (2mm, with Bluetooth data transmission): 990RMB, about $148

3. QNix 4500 (3mm, no Bluetooth data transmission function): 3999RMB, about $590

4. QNix 4500 (5mm, no Bluetooth data transmission function): 5900RMB, about $880

5. Elcometer 456 (1.5mm, with Bluetooth data transmission): 9780RMB, about $1450

6. Elcometer 456 (1.5mm, with Bluetooth and USB data transmission): 12600RMB, about $1880

Through the above introduction, we believe that everyone has a basic concept for the different coating thickness gauge prices. Of course, this is not the instrument model of all three brands. This article only lists six popular products. If you need more detailed information, it is recommended to download the product information through the official website or contact customer service.
