LX shore A hardness is widely applied in the low hardness, all kinds of rubber, plastic, leather, wax and other multiple fat hardness test. ISO868 and ISO7619 international standards of production, with GB/T531, JB6148 and JJG304 standards. Pointer type indicator, reading is convenient, accurate, high precision; handheld design, easy to carry, can be a hand-held measurement, can also be mounted on a supporting test rack test.

Determination of hardness of should be examined before a pointer in a free state should point zero. Such as pointer volume deviation from zero, can loosen the upper right corner of a compression screw, rotating surface, zero. Then the hardness pressure in a glass plate, needle pressing and the end surface of the plantar surface of pressure tight contact with the glass plate, a pointer pointing to 100+/-1HA, if not to the 100+/-1HA, may be slightly pressing the needle pressing several times, such as not to 100+/-1HA, the hardness can not use. As in the Shaw hardness testing machine frame when in use, the handle, so that the table up to the fixed charge weight lifted, so that pressure needle end with pressure foot plane in tight contact with the glass table, pointer pointing to 100+/-1HA. If not a 100+/-1HA, can adjust the work table surface of the adjusting screws, if the pointer is adjusted to 100+/-1HA, it is best to send units of production adjustment is appropriate.
