This instrument that has been developed according to the latest research results is particularly well suited for the following areas of application: Hard material coatings in general, ultra-thin DLC coatings, dirt-repellent coatings (e.g., sol-gel coatings), coatings for PC hard disks and CDs, very thin lacquer coatings, ion-implanted surfaces, nanocoatings for sensors, implants used in the field of medical technology, matrix effects in alloys, biological materials, ceramic materials.

The figure  shows a complete PICODENTOR® HM500 measuring system with the measuring chamber with positioning device and the active anti-vibration table as well as the PC with the WIN-HCU® software The Martens hardness and additional material characteristics according to DIN EN ISO 14577 are measured. The hardness value is computed from the indentation depth that occurs at a specified load. By evaluating the unload plot, one can draw conclusions about the elastic indentation modulus EIT, which for many materials correlates to the usual modulus of elasticity, the Young's modulus. Conclusions about the quality of the nanocoating can be drawn from these and additional material parameters that result from the measurement process.

The design of the micro-hardness instrument combined with the superior evaluation electronics and software allows for a very favorable price/performance ratio.

The resolution for applying the test load is about 100 nanonewton and for measuring the indentation depth about 40 picometer. The maximum test load of the instrument is 500 mN at a maximum indentation depth of 150 µm.

The closed measuring chamber and the active anti-vibration table ensure very accurate measurements with an excellent repeatability precision.
