In this video I introduce my universal hardness tester prototype design. An introduction to the tool and the most common hardness testing methods is given. The reasons for developing this tool are discussed, along with the pros and cons of the individual standardized testing methods (i.e. Rockwell, Vickers and Brinell). Calibration samples are used to demonstrate the result's quality and reliability.
