Making measurement of various stiffness possible
Durometer (rubber / plastic hardness measurement)
·When the base of durometer and work are cohered each other, added pressure caused by spring inside durometer indentation changes shape of work and work makes power against this power.
·Pressed volume of pressed indentation are indicated as stiffness when this added pressure and opposition power are in equivalent.
·The reason why there are various kinds of durometer, it is for the purpose of measuring spongy thing like sponge and hard thing like plastic by combining spring power of strong and weak and shape of pressed indentation (sharp pointed or round).

¦Selection of model of durometer
There are different various types for durometer regarding spring power, dimension and shape of osibari. This is according to each country’s standard for the purpose of indicating degree of hardness and softness with higher sensitivity against characteristic of test material of different surface.
TECLOCK durometer is in accordance with each country’s standard and has completed line-up suiting to wide range of materials including original products. Each durometer such as Type A. D. E. in accordance with physical test method of “ vulcanization rubber and heat plasticity rubber “ JIS K6253 (new JIS ) ruled for the purpose of ISO.
Please refer to the right chart and select the most suitable model.
