Shore A hardness tester is used to measure the vulcanized or thermoplastic rubbers with average hardness. An indentor in the hardness tester is pressured toward the surface of the rubber vertically with the given force applied. The depth of penetration of the indentor forced into the rubber when the face of the pressure foot is in contact with the specimen’s surface is measured. The piercing length is inversely proportional to the hardness: The shorter the penetration depth is, the harder the specimen is, and vice versa.
It is widely used for determining the hardness of semi-finished products and finished products for quality control.
Shore A hardness tester is a portable hand-hold testing equipment featuring onsite measurement without limitation of time, environment and place. In order to heighten the accuracy, some operators use this gauge with an SLX stand together, adding a weight applied to the pressure foot. Both of them can be gainable from Amade.
