NIOS Micro is a new device in the NIOS product line that is designed to perform Vickers micro-indentation in the scale range from HV 0.01 to HV 50. It is certified as a measuring instrument and can be used in scientific and industrial laboratories.

The device implements algorithms for automatic application of indent arrays and measurement of indent boundaries, which allow performing various measurements depending on the tasks set, as well as determining the depths of surface hardening (SHD, Surface Hardering Depth), carburizing (CHD, Case Hardering Depth) and other characteristics.

The design of NIOS Micro is built on the same modular principle as other NIOS hardness testers. If required, NIOS Micro can also be equipped with a nano-indentation module, maximizing the range of forces measured and applicable methods.
