Function:

United States Steve Ember rubber hardness tester/SHORE-A-2-low (double needle type) hardness tester widely used in low hardness of plastics, rubber, plural fat, leather and wax hardness testing. Product reference ISO868 and ISO7619 international standards of production, in line with the GB/T531, JB6148 and JJG304.

Features:


Pointer indicates, easy reading, accuracy, precision Portable design, easy to carry, hand measurements can also be mounted on a matching test, test

Parameters:

Dial: 0 ~ 100HA Dropper on the trip: 2.5 mm Recommended measuring range: 10 ~ 90HA Needle size: 0.79 mm Weight: ~ 0.5 kg Map: Method of use:
Put sample placed in substantial of plane Shang, hold hardness meter, pressure foot in the hole of pressure needle distance try block edge at least 12mm, smooth to put pressure foot pressure in sample Shang, cannot has any vibration, and keep pressure foot parallel Yu sample surface, to makes pressure needle vertical to pressure into sample, by imposed of force to just enough to makes pressure foot and sample completely contact, except another has provides, must in pressure foot and sample completely by touch Hou 1 seconds within readings, if is other interval time readings is must description, In samples from different locations at least 6mm measured hardness value 5 times and take the average.
Terms of use:
⑴, determination of hardness should be checked before the pointer should point to zero-in a free State. Pointer when the deviation from zero, you can loosen clamping screw in the upper-right, turn, zero. And hardness on the glass plate, the pressure pin pressure foot surface in close contact at the time of the glass, the pointer should point to 100+/-1HA, such as when no points to 100+/-1HA, slightly press the pressure pin several times, still not saying when 100+/-1HA, this hardness cannot be used. When used in shore hardness test rack, pull the handle, raise the table to load weight lifting, which is pin closely contact with the foot flat on the glass desk, the pointer should point to 100+/-1HA. When not 100+/-1HA, adjustable work table flat adjustment screw, if adjusted when the pointer is not 100+/-1HA, it is best to send production unit adjustment is appropriate. B, samples and test the temperature requirements of the rubber; ①, rubber thickness not less than 6mm, of a width not less than 15mm, the length is not less than 35mm, thickness less than 6mm, the same film overlap determination, but not more than 3 storeys. And parallel to the film from top to bottom. Secondly, when the test room temperature of 23 ℃ ± 5 ℃, testing hardness stored at this temperature for at least 1 hour before. C plastic sample and the test temperature requirements; ①, plastic specimen is a square with side length 50mm 6mm thick. Also allows 50x15mm of specimens. Secondly, in the case of possible samples before testing should be conducted in a laboratory standard temperature adjustment in accordance with GB/T2941-1991. Comparison test or series of tests must be performed at the same temperature. D, rubber and plastic surface should be smooth, flat, there should be no mechanical damages and impurities and other defects. ⑸, hardness after 35,000 times, recommended that each used around 10,000 times according to GB531 check spring pressure scale and pointer and needle tip shape and size. Services, hardness tester after use, mount the instrument box or equipment inside the tank, placed dry place, avoid wet. ⑺, load lift shaft on the determination and the bottom of the table, note that often wipe clean, apply a small amount of oil to prevent rusting. H, use a shore hardness of time, when a type a durometer values lower than 10HA are inaccurate, measurements cannot be used. Measuring value outside of a hardness meter 90HA type d durometer is recommended.
