Product Description

JBW-C Series Semi-automatic Impact Testing Machine JBW-300C Impact Tester

JBW-C series is PC Microcomputer control, electric pendulum rising, impact; the results are measured, calculated by microcomputers and displayed digitally and can be printed out; having high operation efficiency and high testing accuracy; the energy which is remained after the specimen is impacted broken can automatically rise the pendulum for the next testing; better used in laboratories which make consecutive impact tests or the metallurgy and machine manufacturing sectors which are involved with a large amount of impact tests. the material impact absorbed energy, impact elasticity, pendulum rising angle and average value of tests can be calculated and digitally displayed. The test data and average value of tests of the time can be printed out. via simply by supported beam,the pendulum shaft of hanging pendulum position ,two ends using axletree support,pendulum hang the middyway position of the pendulum shaft, support column front and back symmetry,It has many characteristics such as good stability,great rigidity,simply structure,it doesn’t quiver when hanging pendulum to do impacting test.
