The meter is a gauge for measuring the thickness of varnish coatings with an accuracy of 20 Micrometre. It is used for quick and precise checking whether the vehicle painted in the . The lacquer tester has a colour scale in Micrometre which makes it easy to read the thickness of the varnish or , even for those who check the car for the first time. The tester does not require battery power, calibration and can be used for many years. It is a meter and tester because it performs the function of measuring the thickness of varnish and performs the function of quick testing. It is used to detect the thickness of paint coats that are invisible to the eye on vehicles made of sheet steel and galvanized steel. The tester lets you know if a car accident is under the beautiful varnish. How it works: The thickness of the varnish and is measured by touching the tip of the tester with the magnet of the surface being tested (the surface must be clean and free of dust). Monotonous, not too fast movement, we pull the tester until the magnet breaks from the tested surface. During this operation a colourful scale comes out. The thickness of the lacquer coating is read in Micrometre with an accuracy of 25 Micrometre. The of the measurement is the highest indication on the scale of the tester, and also at this moment the scale automatically disappears. The individual colours on the scale indicate: 1. Black colour - coating with a thickness of over 520 - surface and varnished (the amount of about 0.5 mm). 2. Red colour - coating with a thickness of 300 to 520 Micrometre - surface after sheet metal repairs + a second varnish. 3. Yellow colour - coating with a thickness of 200 to 300 Micrometre - after painting repairs (" second varnish "). 4. Green colour - coating with a thickness of 100 to 200 Micrometre for original varnishes. Warning; in newer car models, 180 Micrometre thic may indicate a thin layer of the second varnish. 5. Blue colour - coating with a thickness of 0.0 to 100 Micrometre - a thin coat of varnish (varnish without foundation or repeatedly ) size:13cm Material:Plastic + Metal colour:As shown Package Contents: 1 * Car Paint Thickness Tester Only the above package content, other are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed is +/- 1-3cm.
