This serial goods are mainly used for the mechanics property test such as the tensile, cutting, bending, compression etc. to various metal and nonmetallic materials. WEW serial testers have been developed according to GB228-2002 "Metal Tensile Test Method" with the adoption of the manual and hydraulic control micro-computer display and electronic measurement. It can automatically process the data and print the test report in accordance with the national standards. WEW serial goods use the micro-computer automatic data collection and processing, synchronous screen display of the test data and curves. It has the functions such as storing in the magnetic disk the test results, printing the test results and curves, processing the batch test result report, managing the database and so on. It also has the network interface. It can automatically seek the multiple technical parameters such as elastic module E ,upper yield strength Reh, lower yield strength REL,stipulated non-proportional elongation intensity Rr,tensile strength Rm,stipulated total elongation intensity Rt,yield point percentaege elongation etc.The serial goods have the features sush as the high precision,advantageous performance,high reliability,convenient operation etc. It completely conforms with GB/T3159-2008 and ISO. , ASTM requirements.
