The material tester is designed to carry out fast and precise color measurements of surfaces. The color ranges CIE-LAB, CIE-LCh, HunterLab, CIE-Luv, XYZ, RGB of the color can be determined with the material tester. An LED with a wavelength of 400 ... 700 nm is built into the colorimeter as a light source. The measuring opening of the material tester is Ø8 mm. Despite its compact design, the material tester has a repeatability of ΔE* from ≤0.1.

In addition to normal color measurement, the material tester can also determine color differences. For this purpose, a reference measurement is first carried out with the material tester on any reference. Then measurements can be carried out on test objects with the material tester. The material tester in turn shows the difference between the reference and the test item. A permissible tolerance can also be stored in the material tester. If the tolerance is adhered to, this is indicated by a green display on the material tester. If the measured color is outside the tolerance, this is indicated by the material tester with a red display.

A connection to an Android capable device can be established with the Bluetooth interface. The free app for the material tester can be downloaded from the Play Store. Measurement parameters can be changed from the app to the material tester. In addition, the measurement can be carried out via the app. The measurement result is then displayed directly in the app. Thus, for example, measurement comparisons can be carried out via the app to the material tester. If measured values ​​are saved on the material tester, they can be read out via the app.

The material tester is therefore used, for example, in quality control in a print shop to check the print result or in the automotive industry to check the paint that has been sprayed on. The battery life of the material tester is approx. 10,000 measurements. If the battery is discharged, it can be recharged in the material tester via the USB-C interface.
