The following is a brief introduction of D-type Shore hardness tester: 

Product name: D Type Shore Hardness Tester 

Product model: LX-D Hardness Tester 

Weight: 160.00g 

Unit of measurement: Tai

Scope of application: General hard rubber, resin, acrylic, printing board, fiber hardness testing, etc.

Shore hardness tester D type hardness tester (rubber hardness tester) is widely used in the hardness measurement of rubber and plastics. It has the characteristics of simple structure, convenient use, small size and intuitive reading. It can be carried with you for hand-held measurement, or it can be installed on a fixed load rack of the same model produced for fixed load measurement.

Measuring principle of hardness tester:        

A steel press with a certain shape is vertically pressed into the surface of the sample under the action of the test force. When the surface of the press foot and the surface of the sample are completely attached, the tip surface of the press needle has a certain extension length L relative to the press foot plane. The size of the value represents the size of the Shore hardness. The larger the L value, the lower the Shore hardness, and vice versa. The calculation formula is: HA=100- L/0.025HD=100- L/0.025HC=100- L /0.025 where HA is Shore A hardness. It can be seen from the formula that the Shore A hardness is related to the displacement of the indenter. By measuring the displacement of the indenter, the Shore A hardness value can be calculated. This hardness tester uses a sensor to measure the displacement of the indenter, and then calculates and processes it by the CPU , Get the Shore A hardness value.

Classification of Shore Hardness Tester: Shore hardness testers are mainly divided into three categories: Type A, Type C and Type D. 

Their measuring principles are exactly the same, but the difference is the size of the measuring needle. The tip diameter of Type A is 0.79mm, The Shore A hardness tester is used to measure soft plastics, rubber, synthetic rubber, felt, and leather. 

 The tip diameter of D type is 0.2mm. That is, the radius is R0.1. The Shao D hardness tester is used to measure the hardness of hard plastics and hard rubbers, such as floor materials, bowling balls and other on-site measurements.

 The C-type stylus is a ball with a diameter of 5mm. Shao C hardness tester is used to measure soft materials such as foam and sponge.

Common sense of maintenance of Shore hardness tester and related accessories 

1) The lifting shaft and the bottom of the worktable on the fixed-load measuring rack should be wiped clean frequently, and a small amount of anti-rust oil should be applied to prevent rust. 

2) After using the hardness tester, put it into the instrument box or instrument box and place it in a dry place to prevent moisture. 

3) After the hardness tester has been used 35,000 times, it is recommended to check the relationship between the spring pressure and the pointer scale and the shape and size of the end of the pressure needle every 10,000 times or so. Shore hardness tester is an instrument for measuring the hardness of vulcanized rubber and plastic products. It has the characteristics of simple structure, convenient use, small size and intuitive reading. The product meets the requirements of GB/T531-1999 and other related standards. It can be carried with you for hand-held measurement or installed in the supporting SLX Shore hardness tester. Used on the test rack.
