Description
- [WIDE APPLICATION]-The hardness tester is widely used to measure the hardness of various soft materials such as rubber, silica gel, tire and plastic.
- [FULL FUNCTIONING]- In the A-type hardness tester, the user does not need to purchase additional special hardness blocks, which saves your cost and makes testing more convenient.
- [DIGITAL DISPLAY] - The hardness tester is equipped with a liquid crystal display to show the test results more clearly and the reading accuracy is higher. At the same time, the alloy probe can be used to input and measure the hardness of rubber and plastic products more accurately.
- [DUSTPROOF DESIGN] - The hardness of the durometer is designed to provide a more accurate reading and a longer service life. Polished design for more comfortable use. The nut is rotatable and fastened. You can choose from hand-held measurements or you can install them on a matching test bench for testing.
- [TEST PRINCIPLE] - The steel pressure with a certain shape is pressed vertically into the surface of the sample under the test force. When the surface of the pressing foot is completely adhered to the surface of the sample, the tip end surface of the pressing pin has a certain protruding length L relative to the plane of the pressing foot, to L The value of the value to characterize the Shore hardness, the larger the L value, the lower the Shore hardness, and vice versa.
Specification: ◆Measurement range: 10-90HA ◆Size of pinhead section :0.79mm◆Pressure Needle Range:0-2.5mm◆Test force 10 (N). Operation Guide: ●The Shore A Durometer: ◆1.Before using, check that the display screen of the hardness tester should show "000" in the free state (if "00" is not shown, you can press the ZERO key to return to zero). ◆2.When the hardness tester is pressed on a flat base level (glass or metal platform), the display screen should show 100 ±1 degree. If it cannot be accurately displayed, the hardness tester cannot be used, and it is best to send it to the factory for adjustment. ◆3.Rubber samples shall be prepared in accordance with the requirements of GB/T531, plastic samples shall be prepared in accordance with the requirements of GB2411, and samples of rubber microporous materials shall be prepared in accordance with the requirements of HG/T2489.★(Tips): If possible, the rubber sample shall be adjusted at the laboratory standard temperature before testing according to the GB/T2941 and GB/T2918 regulations, and then be determined.
