Features:This is a magnetic paint thickness gauge. It?s magnetic tip is extremely convenient in reaching curved surfaces, and in hard to reach places.Its mechanical thickness gauge is water resistant, no batteries needed and can be used in the rain and on a dirty car.Colored gauge shows you exactly what you're dealing with as to thickness of metals and the paint on it, and it will easily reveal any hidden damages.The tester instrument is highly accurate with a micron-level color scale due to its compatibility with digital thickness gauge.Quickly and accurately check if the vehicle has been painted in the past.It?s shaped as a small pen, and is made of high quality materials, making it the perfect choice to carry around and always be prepared.Specifications:Name: Paint thickness testerMaterial:Plastic, metal, magnetColor: As shownSize: About 17.8x7.2x1.7cmQuantity: 1pcThe individual colors on the scale give:Blue: Coating thickness 0.0-100 microns - a thin layer of varnish (no foundation or re-polished varnish)Green: The original varnish has a thickness of 100 to 200 microns.Warning: in newer models, a thickness of 180 microns can represent a thin layer of the second varnish.Yellow: The coating thickness is 200-300 microns after the paint has been repaired (second varnish).Red: The coating thickness is 300-520 microns - the surface after repair of the metal plate + the second layer of varnish.Black: The coating thickness exceeds 520 - the surface putty and varnish (the amount of putty is approximately 0.5mm)Package includes:1* Paint thickness tester
