LX-F hardness tester type sponge factory in order to facilitate customers to measure foam hardness and customized, it is applicable to the determination of soft foam, polyurethane foam products, the hardness and hardness in the determination of the use of different, while in use, press contacts directly on the specimen, and using the weight of its own as a force load.

Stitch range: 0~ 2.5 mm;

Dial: 0~ 100 degrees;

Needle tip: 550mN~ 4300mN (56~ 438.5G).

Handheld devices Center, hardness tester gently in a flat sample is greater than the pressure foot (or specimens), when the hardness of presser foot and sample readings steadily within 1 second of contact when the pointer refers to the scale that was measured (specimen) the hardness value. In order to improve the measurement accuracy, samples should be placed on a flat glass or flat, each measurement point can only be measured once, 25mm or more apart on the same sample different parts of the measuring point is not less than 5 points. Measurement results averaging of the hardness of the material the sample value.

When the hardness of the presser foot is in the free State, the pointer appears as '0', voltage pin end close contact with the presser foot is flat on the glass, should be displayed as the pointer '100'. Check hardness tester pointer does not display when '0' and '100', when you need to adjust '0' and '100' can be used.

(1) the specimen thickness should be between 25mm to 30mm: when thick enough 25mm, 2 pieces overlap, but to ensure that contact surfaces smooth, total shall conform to the specimen thickness requirement.

(2) sample size should meet the length and width is greater than 100mm, 40mm distance from the measuring points and the edges of the sample, each measuring not less than 25mm, each measuring point of the sample of not less than 5 points.

(3) remove the skin on both sides of the sample thickness should be uniform and smooth surface, pore distribution, mechanical damages and impurities.

(4) sample conditioning and testing conditions according to the GB/T2941-91 regulations.

(5) hardness tester after use, put inside a case, placed dry place, avoid wet.
