8 best thickness gauges from AliExpress

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

According to statistics, 90% of cars older than 2 years have minor damage to the body. To hide this, they resort to puttying and touching up the part. Other cars that have been in major accidents are undergoing body repair with numerous welds and putty. Even 30% of new cars have repainted bodies to hide damage from unsuccessful transportation. A thickness gauge will help to detect all this, which estimates the cross-section of the paint layer between the sensor and the base metal.

We have prepared a rating of the best thickness gauges with Aliexpress, which is compiled taking into account customer reviews and product characteristics. Having such a device when buying a car, you can check the seller's words about body repair, find reasons for bargaining, or refuse an unfavorable option in time. The TOP 8 contains already verified products from AliExpress, so such a purchase will be more reliable.

SMART SENSOR AR860

Rating: 4.9

SMART SENSOR AR860

In the first place in the rating is a thickness gauge with Aliexpress in a compact body surrounded by a rubber edging. This increases the protection of the device in case of a fall, which happens quite often during daily use and walking around the car. The large four-line display shows data in microns from 0 to 300 units. This will allow you to find not only the second coat of paint, but also traces of putty. Management is carried out by 7 keys. The owners in the reviews like that you can adjust a certain thickness, after which the sound signal will be triggered. Also, the ultrasonic sensor does not need constant manual calibration, since this is done automatically.

The main advantage for which the thickness gauge with Aliexpress got into our rating is easy access to any parts of the car for taking measurements. This is possible thanks to a remote scanner connected to the machine through a flexible wire. So, the sensor can be easily brought into the engine compartment, into the embossed part of the bumper or on the bends of the sills. This model from AliExpress also has a memory for the last 10 values, so that you can then scroll through the readings and compare the results.

Advantages

  • protective cover on the body;
  • screen backlight in the dark;
  • automatic power off;
  • does not require calibration.

disadvantages

  • very high cost;
  • batteries are not included;
  • only suitable for measuring paint on carbon steel (low-cost auto bodies).

NICETYMETER CM8806FN

Rating: 4.8

NICETYMETER CM8806FN

The second place in the rating is occupied by a product from Aliexpress, made in the form of an inverted bottle. In the wide part there is a black screen on which bright green numbers contrast. The display shows the battery charge level, the current section of the paint layer, as well as the minimum and maximum values ​​with a difference, so that it is easier to navigate when comparing the paint layer in different parts of the machine. The thickness gauge works in two modes: Fe and Nfe. Thickness values ​​can be displayed in both microns and mil. Buyers in the reviews like that the product comes from Aliexpress in a flat case, trimmed with foam rubber inside.

In our opinion, the thickness gauge earned a place in the rating due to the special fast measurement of the paint layer – it takes 0.6 seconds to display the result. This performance will allow you to quickly inspect the vehicle. The measuring range is from 50 to 1250 microns, which is also optimal for professional activities. Thanks to such data, the device with Aliexpress will show any layer of putty, and not highlight an error. The product is also notable for working with both magnetic and non-magnetic materials (body parts made of aluminum and other alloys on expensive cars).

Advantages

  • screen backlight;
  • fast measurement time – 0.6 s;
  • convenient form;
  • weighs 68 g.

disadvantages

  • does not work correctly when the temperature drops to 0 degrees or less;
  • high price;
  • no batteries included.

Misery-770s

Rating: 4.7

Misery-770s

The third place in the rating is given to an almost rectangular thickness gauge with a slight narrowing closer to the sensor. The model with Aliexpress has a white screen with black numbers. In reviews, users like the menu in 4 languages, which increases the ease of use (others only have English). The thickness gauge uses magnetic induction to work with steel, and the eddy current principle is applied to aluminum and its alloys, so the results are highly accurate.

We have rated this gage as the best for professional use. The device with Aliexpress has a compact size of 11×5.3×2.5 cm, so you can carry it with you in your pocket. A case is provided to preserve the thickness gauge during long-term transportation. The model is also equipped with a USB cable and a disk for installing the program on a computer to view and compare values ​​on a large screen. It surpasses the device of other TOP-8 participants and a threshold value of 2000 microns, which comes in handy when detecting body alterations in the engine compartment.

Advantages

  • suitable for steel and aluminum;
  • there is a screen backlight;
  • covers the range of 0-2000 microns;
  • compact dimensions 11×5.3×2.5 cm.

disadvantages

  • sold without batteries;
  • an error of 3%;
  • high price;
  • needs calibration on foil.

SNDWAY SW-6310A

Rating: 4.6

SNDWAY SW-6310A

Our rating continues with a thickness gauge from AliExpress, controlled by four buttons. The screen displays the thickness value, the type of material (magnetic and non-magnetic), the state of charge of the battery and the serial number in the memory where the current result is saved. In total, this model with Aliexpress is able to remember up to 30 measurements. The thickness range is from 0 to 1700 microns. The margin of error here is slightly less than that of other products from our review, and amounts to 2%. It is allowed to work with a thickness gauge at temperatures from 0 to +50 degrees. In order not to drop the device while checking the car, there is a loop on the body, through which a lace is threaded to be worn on the wrist.

We have added this thickness gauge from Aliexpress to the rating because it has a very user-friendly screen. Firstly, the diagonal of the display is 2 inches, which is quite enough to consider the current value of the paintwork thickness even for people with poor vision without glasses. Secondly, the image on the screen turns over as the position of the instrument changes in space, which is convenient for reading readings.

Advantages

  • automatic power off to save power;
  • saves the last 30 measurements in memory;
  • memory is not erased even when the batteries are removed;
  • sound notification.

disadvantages

  • no batteries included;
  • high price;
  • requires periodic calibration with dimes and film.

BENETECH GM100

Rating: 4.5

BENETECH GM100

The fifth place in the rating is taken by a Chinese thickness gauge with Aliexpress in red, equipped with a yellow case. GM100 measures the thickness of the paintwork layer from 12 to 200 microns, so it will 'see' the re-painting of the body, but places with putty, where the section in the dents is more than 300 microns, the device may not recognize and give an error. The device works with Aliexpress from three AA batteries. When they sit down, a message is displayed on the screen. The thickness is measured by ultrasound with a frequency of 5 MHz. The owners like the scanner on the wire in the reviews, which is easy to crawl into hard-to-reach places.

Experts have added the product from Aliexpress to the rating, since it copies the TOP-8 leader in design and characteristics, but at the same time it costs half the price. The body of the thickness gauge has a similar design and arrangement of buttons. The sensor, like that of the leader of the rating, is placed on the wire. Another model from AliExpress is the most 'unkillable', as it is accompanied by a rubber bumper worn on top. This prevents the gauge from cracking or breaking when dropped.

Advantages

  • the error is 1%;
  • attractive price;
  • screen backlight;
  • protective case.

disadvantages

  • periodically requires calibration on the plate;
  • suitable only for measuring paint coat on 'black' metal;
  • if there are no batteries at hand, do not check immediately after delivery;
  • the plastic screen is glued in with air passes along the edges.

RICHMETERS GY910

Rating: 4.4

RICHMETERS GY910

The sixth place in the rating is occupied by a thickness gauge of a narrow, elongated shape. For convenience, the model is worn on the arm and held on the wrist with a drawstring. The device works with Aliexpress both on magnetic steel and on aluminum, accurately showing the size of the paint layer. The measuring range is 0-1300 μm. The device must be applied to the car body directly with its end on the side of the screen. Buyers in the reviews note the convenience of the instructions in Russian, which simplifies commissioning and mastering all functions. Also, despite the budget, the thickness gauge is assembled efficiently and without backlash in the buttons.

When comparing products, we took into account that this is one of the most popular thickness gauges from Aliexpress. The model has over 1000 reviews. Our experts liked the product for its simplicity of operation, for which it got into the rating of the best. Here, as in a wrist fitness tracker, all control is carried out with one button. The second is provided only for turning on and off to save power. Before starting use, the owner only has to substitute the attached films step by step when their value appears on the screen, so that the thickness gauge is correctly calibrated.

Advantages

  • affordable price;
  • instruction in Russian;
  • range 0-1300 microns;
  • simple control with two buttons.

disadvantages

  • no screen backlight;
  • the error is 4%;
  • calibration is required for 5 plates (50, 100, 250, 500 and 1250 microns).

Yunombo YNB-100

Rating: 4.3

Yunombo YNB-100

The sixth place in the rating of models with Aliexpress was taken by a thickness gauge from an amateur series, made of ABS plastic. Case dimensions 3.6×8.3×2.2 cm allow you to carry it even in a breast pocket. The device weighs 64 g, which almost does not stretch the pocket. The device works on the principle of magnetic induction and is applicable for detecting paint and putty in the thickness range 0-1300 microns. The product is delivered from China in a paper box with a cloth cover. Despite the low cost of the thickness gauge, the screen is backlit, although this is a rarity in models of this level. Users in the reviews share that the display of the result can be configured both in microns and in millimeters.

The experts included the thickness gauge in the rating because it is the most affordable model from Aliexpress, which does not need calibration. The device has everything necessary for automatic adjustment, so the owner does not have to carry out the test with the plate holder for the scanner. But magnetic technology is only suitable for checking the bodies of inexpensive cars, which must be taken into account when choosing.

Advantages

  • compact dimensions 3.6×8.3×2.2 cm;
  • range 0-1300 microns;
  • manual in Russian;
  • LCD backlit screen.

disadvantages

Rating: 4.2

All sun EM2271

Our rating ends with a thickness gauge from Aliexpress, which looks more like a keychain. This unique product is made in a blue oblong case and can easily fit on a keychain due to its dimensions. There are two buttons for control. The thickness gauge weighs only 23 grams, so it doesn't feel at all in your pocket.
