Paint thickness gauge

Paint thickness gauge – a few words

The varnish thickness gauge is used to measure the thickness of the varnish layer on steel, galvanized steel and aluminum. It is perfect for checking cars, whether they have not been putty or painted twice.

Colloquial naming

The varnish meter is also known under other names such as: “varnish tester”, “varnish sensor”, “thickness gauge”, “coating thickness gauge”, coating thickness gauges “varnish gauge”, varnish thickness tester, varnish thickness gauge.

How it’s working?

The meter measures the thickness of a non-metallic layer (varnish, putty, plastic, etc.) on a metallic substrate (steel, galvanized steel, some aluminum models). The meter actually measures the distance from the sensor surface to the metal surface.

Measurement technique

The meter is equipped with a measuring element. Depending on the version, it is placed on the body of the varnish thickness gauge or on the cable in the probe. To make a measurement, apply the probe to the test surface, press it perpendicularly lightly. In less than a second we will get the measurement result on the display. The test should be carried out on a clean surface for a simple reason, when the dirt is on the varnish then the meter will measure the thickness of the varnish and dirt.

How to measure varnish thickness correctly?

The test (measurement) of the vehicle should be started from the roof and then made several measurements on each element of the car (the more the better). The thickness of the original varnish (coating) on ​​the car should be in the range of 80 μm – 180 μm and on one vehicle it can deviate up to 40%, while the second layer of varnish is measurements twice higher to 400 μm in the case of even higher values ​​we deal with a putty. If doubts arise, then the right side should be painted symmetrically with the left side, if it does not help, then it should be compared with the second same car model and yearbook.

The MGR-10-S-AL paint thickness gauges allow you to measure the paint thickness of all cars available on the market, including those with aluminum bodies e.g. Audi A8, Audi A2, Jaguar XJ or aluminum body components such as bonnets and fenders e.g. Opel Vectra C, Opel Insignia, Citroen C5, Volvo V50, Volvo S40, Subaru STi, BMW 5, Audi A6, Mercedes E211, Mercedes-Benz W204, Jeep Grand Cherokee, Chrysler Voyager, Renault Laguna, Renault Clio. It automatically recognizes the type of substrate by communicating on the display: (AL) Aluminum, (Fe) Steel.

Will the meter measurement damage the paint?

The paint tester is safe and has a specially designed measuring element made of plastic that is delicate for the paint.

What if the seller wants to tell you that the paint tester is broken?

Along with the varnish thickness meter, a calibration plate covered with a 200 μm foil is included, thanks to which you can always be sure that the meter is working properly. If necessary, the customer can easily calibrate the meter to correct the measurement error.

The varnish meters turn off automatically in the case of low batteries, then the message “low battery” will appear on the meter display, then the batteries should be replaced with a new one. This prevents erroneous measurements when working with a weak power supply.
