FUNCTIONAL FEATURES

Main Test Unit 

Main functional test unit employs flexible design to layout tensile test space above main test while compression test space is located under main test unit, which enables this tensile tester deserves its name as universal material test to implement various tensile, compression, shearing test projects. 

Drive System

Drive System, with excellent innovation of motor with gearbox, chain drive mechanism, secondary screw drive to control the elevation of lower crossbeam to regulate tensile, compression space. 

Hydraulic System

The hydraulic fluid, in hydraulic fluid container being forced into fluid pipe by performing of motor to drive the high pressure pump, flows and passes through one-way valve, high pressure oil filter, differential valve assembly, servo valve and into hydraulic cylinder. The computer will send control signal to servo valve to control the open and direction of servo valve, which will control the flow quantity of hydraulic fluid into hydraulic cylinder so as to achieve constant velocity testing force as well as displacement control. 

Software System

Available for Tensile, Compression, Shearing, Bending test as well as other tensile test;

Available for open program testing, program standard & program testing flow, and compatible for inputting and outputting test, standard and flow;  

Available for testing parameter customization;

Open EXCEL version testing report as well as user customize testing report format;

Available to search, print testing result, compatible for multiple-test specimen testing report printing as well as custom reordering and printing testing report; 

Software system designed with powerful testing analysis function;

Limit access can be available by limiting user authorization as administrator and tester;
