ANALOG JAPAN RUBBER HARDNESS TESTER
Durometer (Rubber Hardness Tester)
Make: Kori Seiki (Japan)
This is a spring type durometer which can measure the hardness of rubber and plastic products such as tire, sponge and felt at a high accuracy. This equipment is conforming to JIS (Japan International Standards) and Internationa Standards and makes it possible to make measurement easily in a short time.
This durometer distorts the surface of specimen by pressing an indentor against the specimen surface by the spring force, and measures the hardness based on the "depressed amount of indentor" when the balance is kept between the resilient force of specimen and spring force.
