Digital Durometer Shore Hardness Tester High Precision with Automatic Zero Function Portable and Suitable for High Hardn

Description The Shore Rubber Hardness Tester is an instrument for measuring the hardness of vulcanized rubber and plastic products The instrument has three types Type A Type D and Type CType A and Type D are respectively suitable for testing low and medium hardness and high hardness materials Type C is suitable for testing the hardness of microporous materials for shoes made with a combination of rubber and plastic when the compression is 50 and the stress is above 0 049MPa The plastic contains foaming agent Features Type A is suitable for general rubber synthetic rubber soft rubber polycarbonate leather wax etc Type C is suitable for microporous materials made of crispy and crisp plastic containing foaming agentType D is suitable for general hard rubber resin acrylic glass thermoplastic rubber printing plate fiber etc Specification Dial value 0 100 degreesNeedle stroke 0 2 5mmPressure at the needle end A C type 0 55N 8 06N D type 0 44 5NInstructions Place the sample on a solid surface and hold the hardness tester The indenter should be at least 12mm away from the edge of the sample Press the indenter firmly on the sample and press the indenter vertically into the sample until the indenter is completely Reading within 1S upon contact Test the hardness value 5 times at different positions with a distance of at least 6mm between the measuring points and take the average value the distance between the measuring points of the microporous material is
