Designed with the vision of providing clients with ease of use, longevity with low maintenance cost and especially high accuracy; the Micro Module achieves this with its unique combination of motor actuator, sensitive load cell and a large surface capacitor, all vertically aligned for maximum stiffness. Because the load applied is measured directly at the actual surface, measurements can be made in true closed control feedback loop. This feature is essential to react quickly and accurately to fast events such as during scratch and wear testing or when fractures occur during indentation. The sensitive load cell is also straightforward to calibrate with a direct weight scale. Therefore, every the module can be quickly calibrated, by the user, in less than 15 minutes for Load, Depth and Compliance. This ensures constant accuracy of the data through time and from one instrument to another. The capacitor works up to a range of 1mm,  above this the displacement of the motor up to 50mm can be used as a depth sensor to extend the capability of the system on materials such as  thick foam. A range of load cells choices are available from, 20N to 400N with  testing capability to below 10mN.


The module provides micro scale testing during indentation, scratch and wear testing modes. Each mode of testing provides a wide range of testing that can provide properties such as hardness, creep, elastic modulus, stress-strain curves, yield strength, fatigue, fracture toughness, wear rate, friction coefficient, scratch and marring resistance, plastic/elastic deformation among other tests. In combination with integrated x-y motorized table, one can test at very specific locations or do a full mapping of properties across a chosen area. The higher loads are ideal for testing hard coatings (DLC, TiN, TiC) such as the one used in the tooling industry. However the more sensitive loads of the micro range are ideal for the characterization of industrial coatings; ranging from plasma processed layers used in semiconductor and optical technology, to decorative and protective coatings used for automobile parts and consumer  goods.
