Portable hardness testers or bench hardness testers are the most suitable tools to check hardness of materials.
Portable hardness testers can be of different types, depending on the type of material or test to be carried out. Leeb hardness testers, for example, use the Leeb principle to determine elastic properties of various metals and alloys, and can measure in different scales, such as HRC, HB, HV. They are mainly employed to evaluate the hardness of material arriving from suppliers, for quality control in production line and for maintenance of structures and parts subject to wear.
Shore hardness testers fall into the category of portable hardness testers. They are widely utilized to detect the hardness of rubber, plastic, sponges and related materials. Shore hardness testers can be of different types depending on the measurement scale. For example, shore A hardness testers are mostly used to measure the hardness of soft materials such as rubber, elastomers, and other rubbery materials such as neoprene, silicone and vinyl. Shore D hardness testers are utilized to measure materials such as plastic, ant, epoxides and plexiglass.
Among portable hardness testers suitable for measuring the materials hardness, there are other types such as Barcol hardness testers, Webster hardness testers and ultrasonic hardness testers.
