Instructions:
The sample on strong 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 x Rubber Tire Durometer
