We select a thickness gauge on "AliExpress": 14 best devices for a car enthusiast and a professional

The thickness gauge is a unique device that is widely used in the work of auto-painters. A simple layman, he may not be needed, but when buying a used car you can not do without it. In the list of 15 best thickness gauges with "AliExpress" you can find both budget models and professional devices at a rather high price.

Thickness gauges and their types

A thickness gauge is understood to mean a special device for measuring the thickness of paintwork, soil, putty and even rust. Thickness gauges work without damage to the structure and integrity of the surface layer. Despite similar results, products can have different operating principles and, depending on this, are divided into the following groups:

  1. Eddy currents. Perfectly suited for aluminum, alloys, copper, have a minimum error. They work by means of an inductive effect on a metal (in a magnetic field). The thicker the coating layer, the lower the signal will be.
  2. Magnetic and electromagnetic. The simplest devices that provide information on the degree of attraction to the metal. They may have a significant error, oriented to the use of ferrous metals, which have magnetic properties.
  3. Ultrasonic The most modern thickness gauges, characterized by a minimum error (less than 3%). Reliably reflect the necessary information: the size of the coating layer, the type of base, its thickness. Perfectly suited for measurements on wood, plastic, glass, other non-metallic materials, as well as on any metals.

Purpose and advantages of thickness gauges

In everyday life, thickness gauges are most often used for measuring the coating of a car body. Their benefit to the future car owner is huge, especially when buying a used car. There are frequent cases when the seller claims that the car did not get into an accident, was not painted, and after a while the new owner finds rust, scale, and putty layers.

With a thickness gauge, such problems can be avoided. This device will immediately identify the areas of straightening, re-puttying and manual finishing with repainting. The actual wear of the car, the degree of mechanical damage and geometry disruption cannot be hidden from the thickness gauge, moreover, it will make it possible to easily determine the honesty and decency of the seller and draw appropriate conclusions.
