Measurement range and accuracy
The range of up to 1300 µm covers thicker coatings that may occur after a repair or as part of a special surface treatment. A layer exceeding the upper limit is outside the gauge’s measurement range.
The stated accuracy of 2 µm is a useful parameter when comparing readings. On its own, however, it does not guarantee that the gauge can reliably distinguish between two layers that differ by 2 µm under all conditions. Results should also be considered in light of the substrate, the condition of the surface and whether the gauge is used correctly.
Measuring metals, including aluminium
Aluminium support is useful when inspecting vehicles with components made from this material. The TC100 can also be used on other metal surfaces; check the device instructions to confirm compatibility with a particular substrate.
When inspecting a vehicle, comparing readings at different points can highlight uneven coating thickness or an area worth examining more closely. Thickness alone does not establish the quality of the paint or the cause of a difference. A higher reading may be associated with a repair or another surface treatment, but it cannot support a definite conclusion without further inspection.
Before measuring, follow the device’s calibration and operating instructions. When comparing results, also consider whether the readings were taken on the same type of substrate and whether the surfaces are in comparable condition.
Display and controls
The TC100 has a display for the information needed during measurement and is operated with four buttons. Readings can be checked on the spot, which is useful when inspecting a car or other painted metal objects.
Listings and user reviews
The original overview described the TC100 as an affordable gauge offered on AliExpress, with more than 500 orders and positive reviews. Availability, price, order counts and ratings can change, however. Neither orders nor reviews alone confirm the gauge’s accuracy or quality.
The R&D TC100 stands out for its measurement range, aluminium support and straightforward controls. It is suitable for preliminary checks and comparisons of paint thickness, provided results are interpreted with the limits of the gauge and the particular substrate in mind.
