info@ndtone.comSPR-A (Portable Rockwell) probe
Description
The probe is designed to measure the hardness of non-ferrous metals and alloys (aluminum, copper, titanium and their alloys, etc.), all types of steels and alloys of low and medium hardness (structural, carbon, alloyed, stainless, heat-resistant, etc.) and other materials (fiberglass, engineering plastics, etc.).
The SPR-A probe is completely identical to the SPR probe and is equipped with an automatic load application module. In this case, when making measurements, the operator will not need to make efforts to take measurements, it will only be necessary to hold the probe on the surface whose hardness is to be measured.
The measurement is started by pressing the button located on the top cover of the module. By automating the process of applying the measuring load during the measurement process, the human factor is eliminated, the repeatability and reproducibility of the measurement results is increased.
The automatic load application module is powered by a built-in Li-Ion battery.
