GWA Series Computer Control Hydraulic Servo Steel Strand Tensile Testing Instrument/Equipment/Machine
This series of machines adopt high precise electro-hydraulic servo valve to drive precise hydraulic cylinder, realizing auto control of constant speed load, constant speed displacement, constant speed deformation etc. and complete tensile test of steel strand specimen. They comply with national standard GB/T5224-2003 steel strand for prestressed concrete and can test tensile strength, non-proportional extension strength, elastic modulus, elongation and other mechanical properties for steel strand.
