SUNDOO Instruments LD-A Digital Shore Hardness Tester is a portable A-type Shore Hardness Tester, which integrates measuring device and data processing. LD-A digital display Shore Hardness Tester is mainly used to measure the hardness of soft plastic, rubber, felt, leather, printing rubber roller and other pixel materials. LD-A digital display Shore Hardness Tester has the advantages of accurate measurement, compact structure, low power consumption and easy operation. It is more and more widely used in the field of material hardness testing.
A steel indenter of a certain shape is vertically pressed into the surface of the sample under the action of the test force. When the surface of the presser foot is completely attached to the surface of the sample, the tip of the indenter has a certain protruding length L relative to the plane of the presser foot. The measured hardness is represented by the L value, the larger the L value, the lower the hardness, otherwise the higher the hardness. The principle is as follows:

1. Real-time tracking value measurement;
2. Peak hold measurement;
3. Automatic timing measurement;
4. Automatically store and calculate the average measurement;
5. The power-saving design of automatic shutdown without operation, and the shutdown time can be set freely;
6. Battery underVoltage prompt;
7. Through the RS-232C serial port and the computer for data communication, the supporting software displays the measurement curve.
