Model overview based on user reviews
The Yunombo YNB-100 is a compact and affordable coating thickness gauge that offers high accuracy in detecting additional layers of paint or putty. It features a backlight for easy reading, comes with a case, and allows for the selection of measurement units. Users appreciate its ability to identify small touch-ups and transitions, making it a reliable tool for various applications. However, it is important to note that in severe frost, the device may lose charge quickly, so carrying spare batteries is advisable. Overall, the Yunombo YNB-100 is a cost-effective option that performs comparably to more expensive models, with a minor accuracy difference of about 5 microns.
Pros
Cons
In comparison with more expensive counterparts, there is not much difference, I compared it with a friend's model for $ 150, the difference is plus or minus 5 microns. With this thickness gauge, you can easily find not only putty, but also places of small touch-ups. On an uneven surface, it must be applied as perpendicular as possible so that there is no error. In the photo where the thickness is 250 microns, there is just a small tint, this is already the place where the transition was, the threshold was tinted from below, the device showed perfectly. In general, this little helper eliminated 5 cue balls. It is powered by two small CR2032 batteries, I would carry spare ones with me, because in the cold they can run out very quickly and until they warm up, there will be little sense, this device does not like frost. – accuracy – presence of backlight – case included – compactness – selection of measurement units – price - in severe frost after 7 minutes loses charge  Bogdan K: use Yunombo YNB-100 few months |
Convenient and stable coating thickness gauge, perfect for quickly checking the paint or varnish on a car or metal. The device is lightweight, compact, and operates simply by "turning it on - applying it - checking it." * Can measure coatings on different bases: magnetic (Fe), non-magnetic (NFe), and galvanized (Fe+Zn); * Range up to 1800 µm with a resolution of 50 µm — enough to detect factory painting and an additional layer/putty/repainting; * Does not require calibration and is immediately ready to use; * Very compact and lightweight. * Significant measurement errors. Not suitable for professional use; * Basic functions without memory and other conveniences; * CR2032 batteries discharge fairly quickly. Ruslan ShiZ: use Yunombo YNB-100 more than year |
it may not precisely determine the thickness of the paint, but it definitely identifies if there is a second layer or not, and I think that's exactly what it's made for. Accurately detects a second layer of paint or putty. no  arm: just bought Yunombo YNB-100 i recommend it should buy |
