The best thickness gauges for paintwork, top-10 rating of thickness gauges

When a person is going to buy a car from a previous owner, it definitely will be interested in a number of important points: visited whether the vehicle is in an accident, all body parts factory or some of them have been changed, repainted them, and if so, why? It is almost impossible to answer these questions correctly, even with a thorough visual inspection. Special equipment called a thickness gauge will help you do this. This device is designed to calculate the thickness of the paintwork.

It is not uncommon for sellers to try to hide the fact of replacing certain parts from a potential buyer. In order for the car to have an attractive appearance, the so-called pre-sale preparation is carried out, which consists in repainting body parts. This allows you to achieve an excellent visual effect, it will look like the car has not been in road accidents, has not been painted, and so on.

On the Internet, you can find the average value of the paint layer for each make and model of car. Armed with this knowledge, you can use a thickness gauge to determine this parameter on most of the main elements of the vehicle within a few minutes and calculate where the putty or an additional layer of paint was applied. Automotive stores today offer their customers a wide range of thickness gauges, which differ from each other in the principle of operation, functionality and a number of important points.

Buying the optimal model is not as easy as it seems at first glance. To make this task easier for you, we decided to dedicate our review today to this particular product. However, before we start considering specific models, let’s look at what the equipment works on, what capabilities it has, and so on. That’s where we’ll start.

What do you pay attention to when buying a thickness gauge?

The simplest device for calculating the thickness of a layer of paint and varnish materials can be made with your own hands – take an ordinary magnet and wrap it in a cloth (this protects the paint layer from scratches). The principle of operation is quite simple – on normally painted surfaces, the magnet will hold, and from the plastered ones it will fall off. This is due to the weakening of attraction due to non-magnetic repair material. A serial arrow thickness gauge works on a similar principle. It is quite simply arranged, therefore, it will serve for a long time. The simplicity of the design ensures low cost, there is no need to provide power. However, such a product has a number of significant drawbacks that negate all its advantages: it is not very sensitive and is not able to provide good accuracy of indicators.

A more advanced design is an electromagnetic thickness gauge, which works by creating a magnetomotive force on the winding. Here, measurements are made by calculating changes in the electromagnetic field – a Hall effect sensor is used for this purpose. The accuracy here is much higher, as is the sensitivity of the device, but the cost also increases.

The most expensive, but at the same time the most accurate equipment, is an ultrasonic thickness gauge, the operation of which is not associated with the use of magnets at all. This device can measure the thickness not only on metal, but also on plastic elements of the body, for example, on bumpers. The principle of operation is based on passing a high – frequency sound signal through elastic and solid media and returning it back to the device-an echolocation base. Such products are usually used by professional craftsmen who are engaged in the restoration of body elements after an accident.

Choosing models for our rating of the best automotive thickness gauges of 2021, we were guided not only by the factors listed above, but also by user reviews, as well as the ratio of price and quality of equipment, so that it turned out to be affordable for most of our readers. Now is the time to analyze the useful characteristics of such devices.

The best thickness gauges for paintwork, top-10 rating of thickness gauges

This design is designed specifically for calculating the thickness of products made of homogeneous materials, such as metals, cast irons, alloys, plastics, paint coatings, rubber, and so on. Measurements can be made even if the product is only accessible from one side. In addition, this equipment is used to determine the speed of propagation of ultrasonic waves in the product environment. The thickness is measured by the contact method – the ultrasonic transducer is pressed tightly against the surface of the object, and there must be a layer of contact liquid. Its quality is water, alcohol, oil, various kinds of lubricants.

In the process of performing the work, you can use a variety of converters, and you do not have to configure the device in addition. The thickness sample is built-in, if necessary, the device is calibrated on a sample whose thickness is known in advance. The interface is intelligently clear, there is a convenient menu for selecting the operating mode. The device is characterized by insignificant overall dimensions and low weight. The device is quite economical – on one set of three batteries, it can last up to one year with regular use. If you do not plan to use it too often, then this period increases significantly. The liquid crystal monochrome display has a battery charge indicator. The device can work in quite harsh conditions – at temperatures from -30 to +50 degrees. The menu is Russified, the case is plastic, the Assembly is high-quality: all elements are tightly fitted to each other, there are no extraneous creaks and backlashes.

  • Consumes a small amount of energy;
  • Large internal memory – the product can store up to 1000 measurement results;

The plastic itself has a matte finish, so it will not remain all sorts of dirt, fingerprints, and so on. Special shock-absorbing inserts are provided on the sides, which will not allow the product to slip out of the user’s palms.

The kit includes a case for storage and transportation, which will additionally protect this equipment. When the set range is increased, a beep will sound. On the front side there are two buttons that can be used to set the minimum and maximum thickness of the paintwork. The display is liquid crystal, equipped with a very convenient led backlight. The device’s memory is designed for the last 80 measurements, and the data will not only be stored there, but also undergo special processing, on the basis of which usage statistics are formed. The product comes with a cable that allows you to connect the device to a personal computer and transfer data there using special software. In addition, there are two samples (one made of steel, the second of aluminum) that allow you to calibrate the equipment.

  • When turned on, the device performs a self-diagnosis, and it takes only a couple of seconds;
  • There is a backlit display for easy operation;
  • Despite the operating technology, the accuracy of the data is quite high;
  • There are samples that can be used to configure the equipment;

3. Aktakom ATA 7156

The best thickness gauges for paintwork, top-10 rating of thickness gauges

Like most universal devices, this thickness gauge uses two main principles in the course of its operation – eddy current and magnetic. The first one is designed to work with non-ferrous metals, the second one is used for steel. The product is widely used among mechanics that carry out car body repairs. This equipment is often used by independent appraisers, who are very important to quickly determine whether the car was in an accident, whether it was repainted.
