【Product Features】
1. Has a colour scale in microns.
2. With magnetic tip, it can stick to any curved surface or a hard-to-reach place.
3. The thickness of the varnish and putty 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).
4. For measuring the thickness of varnish coatings with an accuracy of 20 microns.
5. Quick and precise checking whether the vehicle was painted in the past.
6. Used to detect the thickness of paint coats that are invisible to the naked eye on vehicles made of sheet steel and galvanized steel.
7. Does not require battery power.
8. Fine workmanship.
9. Water resistant.
10. High accuracy and reliability.
11. Convenient to use.

【Different Color Shows】
Blue Color: coating with a thickness of 0.0 to 100 microns - a thin coat of varnish (varnish without foundation or repeatedly polished)
Green Color: coating with a thickness of 100 to 200 microns for original varnishes. Warning; in newer car models, 180 micron thickness may indicate a thin layer of the second varnish.
Yellow Color: coating with a thickness of 200 to 300 microns - after painting repairs ("second varnish").
Red Color: coating with a thickness of 300 to 520 microns - surface after sheet metal repairs + a second varnish.
Black Color: coating with a thickness of over 520 - surface putty and varnished (the amount of putty about 0.5 mm).
