3.Main features :
1) The host adopt high rigidity structure, which can guarantee the safety in the process of the test .
2) Load cylinder up-setting type , working bench height 500 mm, easy to take put and down the covers specimen .
3) The rigid block and piston end are connected by knuckle ball, ensure the reaction plate and manhole cover is entirely contact , guarantee the authenticity of the bearing capacity can be measured .
4) Cylinder and piston sealed with special material , high sealing, low friction and long use life.
5) Adopt professional testing machine oil pump motor group, low noise and long use life .
6) Adopt super refined oil filter ,ensure the inside oil system clean ,so as to guarantee execution control long-term work element .
7) Computer automatic control, real time display the current value of force, peak, test process information .
8) Real-time recording test curve, high speed sampling ;
9) Equipped with data, report processing function , provides users a GUI-oriented specialized editing tools for test reports ,with the characteristics of flexible operation, easy to learn, can print test curve and test convenient value ;
10) Contains a variety of control methods, include constant stress, constant deformation, constant displacement ,constant force and other closed-loop control ways . Curves include force-time and others recorded simultaneously ,can switch to observe at any time .
11) The software set automatically value reset system, eliminate artificial reading error .
12) Overload protection, when the force or displacement exceeds the machine rated value, the machine will unloading or stop test automatically .
13) The failure load and deformation value are automatic collection and print statements.
14) Available to users of professional "Program Control Editor" software, in which can edit specific control program according to the actual needs flexibility . in the bottom edge end measurement, data accuracy and stability.
