Product specifications Type: Type A Calibration value: 0-100HA Total force of measurement: 8.1N External pressure: 1KG Pressure head shape: Presser cone top angle 35 degrees Needle length: 2.5mm Product features Shore hardness tester is a relatively sophisticated measuring tool for measuring the hardness of rubber and plastic. ISO 868-1986 Plastic and hard rubber, hardness measured by Shore hardness tester. ISO 7619 rubber, the indentation hardness was measured using a Shore hardness tester. Digital display,easy to read and high accuracy, Handhold design, carry conveniently. LX-A is suitable for testing the hardness of medium and low hardness plastics, leather, various rubbers, multi-fat, wax. Instructions The thickness of the test specimen shall be greater than 6 mm. When it is not more than 6 mm, it shall be stacked with the same material, but not more than 3 layers. The test area shall not be less than the edge of the pressed foot (18 mm in diameter). Hold the hardness tester with hand and make the pressure foot and the sample evenly pressed (using pressure 1kg), the reading indicated in the table at 1 second, to measure the hardness of the sample by the average of the three points.
