The WEW-B series microcomputer screen display hydraulic universal test can achieve rapid tensile testing operation. It has three closed-loop control methods: test force, deformation, and displacement. It can achieve automatic test process control according to the set program, and smoothly switch between different control methods. It can achieve constant velocity loading: constant velocity test force test, constant velocity displacement test, constant velocity deformation test, etc. This product is suitable for tensile testing of materials, mainly focusing on tensile testing of metal bars and plates
The measurement and control software of the microcomputer screen display testing machine can achieve automatic collection and processing of test data, real-time display of test data and various test curves such as stress-strain curve, test force deformation curve, test force time curve, etc. It can save, output, and print test reports and data in the format required by users.
