Shore Durometer Hardness Testing
Shore durometer testing is a standardized way to measure the hardness to ensure the product quality of rubber, elastomers, polyester, leather, pressure rollers, hardboards, wood, plastics and more.
The shore durometer is an internationally recognized measurement standard for hardness testing. Shore hardness is expressed by a number ranging from 0 to 100 on a Shore durometer scale. Higher numbers indicate a greater resistance to indentation. The higher the number on the scale, the harder the material. Lower numbers indicate less resistance, thus softer materials. Shore “A” scale durometers are used for softer materials, and Shore “D” are used for hard materials.
Which durometers offer the highest precision in the market?
The HP Analog Durometer hardness tester from Bareiss, the most popular hardness testing equipment, sold 500,000 units worldwide.
For over 65 years, Bareiss has produced a variety of hardness testing instruments. Bareiss’ wide range of material testing equipment is used in the food, pharma, plastics & elastomers industries. Quality has always been one of the essential pillars of Bareiss; thus, the testing equipment is engineered and manufactured in Oberdischingen, Germany. Even raw materials are brought into the production building and are machined in-house.
Every unit of the Analog Durometer is carefully assembled and calibrated by Bareiss technicians. The durometer measures the depth of an indentation in the material created by a given force on a standardized presser foot. This depth depends on the material’s hardness, viscoelastic properties, presser foot’s shape and the test’s duration. It combines different size bearing balls to create smooth travelling for the indenter to prevent the indenter from travelling with friction.
The entire chassis of the HP Analog Durometer is made of aluminum, providing lightweight and durability. An Analogue Durometer’s great advantage is the precise indication of its measured values. The HP Analog durometer hardness tester can be used as a portable instrument or with our tabletop test stand. Bareiss’ HP durometer series is available in different Shore and non-Shore scales and with the possibility of a customized presser foot to suit different requirements.
