Type A is sui for general rubber, synthetic rubber, soft rubber, poly fat, leather, wax etc. The type O is sui for the micro-porous materials made of foaming agent in the plastic. Type D is sui for general hard rubber, resin, acrylic, glass, thermoplastic rubber, printing plate, fiber etc. Specifications:TypeOptional: A, O, D Dial value: 0-100 degrees Pressure needleip: 0-2.5 mm Pressure needle end pressure:A/O type: 0.55 N 8.06 N,D-type: 0-44.5 N Accuracy: 0.1 mm Test force: 0.5 N Size: 78 * 52 * 22 mm/3.07*2.05*0.87inch Weight: 200 g Insuctions:The sample on song plane, take the hardness tester, pressure needle distance sample at least 12 mm edge smooth put pressure on foot pressure in the sample, makes the needle vertical pressure into the sample, until the feet and sample completely contact pressure when within 1 s reading. Measuring at least 6 mm apart in different positions of the measurement hardness value 5 times, take the average micro porous materials are measuring at least 15 mm. In order to stabilize determination conditions, to enhance determination accuracy, hardness tester device should be in the same determination on supporting producer determination.Package Included:1 xRubber Tire Durometer h2 Note: normal;Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering./h2
