The TC100 paint thickness gauge is a compact digital device designed to accurately measure the thickness of coatings and paints on metal surfaces. Using electromagnetic induction and eddy current principles, it automatically detects the substrate type and is suitable for both ferrous (Fe) and non-ferrous (NFE) metals. Ideal for checking the condition of car paint before purchase or repair.
This coating thickness gauge is ideal for car buyers, auto repair shops, painting workshops, and quality control specialists. Simply place the device on the surface to be tested – it will automatically determine the substrate type and display an accurate result on the screen. It is useful for both professional work in manufacturing and for home use when buying a used car or checking the quality of repairs.
Question: What materials can this device measure?
The device is suitable for measuring coating thickness on ferrous (Fe) and non-ferrous (NFe) metals, such as paints or enamel on steel, paints and anodized coatings on aluminum or copper.
Question: Does the battery come included?
No, a 9V battery is not included in the package. It is recommended to purchase it from a local store or shopping center before using the device.
Question: What is the measurement accuracy limit?
The device provides a resolution of 0.1 µm and can measure coating thicknesses from 0 to 1300 µm, making it suitable for both thin and thick coatings.
This coating thickness gauge is a reliable and accurate tool for monitoring the condition of car paint, manufacturing quality, or metalworking processes in any environment.

I have bought this thickness gauge many times before, and this time the device showed more accurate readings on an iron plate and test standard substrates. I think it will show equally accurate readings on a machine. Thank you to the seller for such a high-quality instrument.

Received the order. Delivered in just 5 days, the thickness gauge matches the description, includes calibration plates and a case, made with high quality, battery not included in the order. Already tested it a bit, there is a slight measurement error, you need to align it without deviations from the plane, then it will read correctly, it fulfills its task. Overall, for the money, it’s a very good performance. I recommend the store! Thank you!

Super Lackdicken measuring device! It even automatically switches what it should detect! And the device is 100% accurate. The only criticism would be that there is no illuminated LCD, but for that price it’s great!

Works fine. I confirmed my suspicion based on a visual inspection of my car that some panels had been repainted. It measures consistently, and I also tried it on another car, knowing that certain parts were repainted compared to the original paint, and it showed the difference in paint thickness. A useful tool.

The zero point adjustment is easy and accurate. The measurements are stable, and there's almost no error even with repeated measurements. I've used other measuring instruments worth over 100,000 won, but this product seems superior. It's an excellent performing product for its price.

A good thickness gauge. Everything included in the package is present. We installed a new battery (CR2032), calibrated it, and it works. We’ve been using it for many years, which is why we bought this particular model again. The reason we bought a new one: in the old thickness gauge, when replacing the battery, one of the terminals stopped snapping into place, so we opted for a time-tested model. We are satisfied with the product.

calibration using several plates of different thicknesses. detects steel or non-steel – displays this on the screen. simple and sturdy. 9V battery to be purchased separately.

Automatic recognition of non-ferrous and ferrous metals / Even with factory settings, the values are shown within the error range / There are cases where the values slightly exceed the error range at 50um for non-ferrous metals, but the remaining range from 100 to 1000um is shown within the error range / With this level of performance at this price, it appears to be the best value for money.
