Computerized Hydraulic Servo Universal Testing Machines

Computerized Hydraulic Servo Universal Testing Machines

Technical Specification

The microchip controlled Electro-hydraulic servo universal testing machines is mainly designed for tension, compression, flexure, shear on metal, and non-metal materials. This product series features a bottom-mounted hydraulic cylinder; electrically adjusted test space, hydraulically powered automatic grip, and adjustable four-column main frame. It is competent to fulfill the requirements of application fields such as road, bridge construction, construction materials, quality control department, science and research department, iron forging, higher education, etc.

This product is applicable to tension on metal bar, plate and threaded iron, or high speed wire rod, steel strand (related accessories required), tension on high strength, high hardness metals and compression on metals or concrete. This series is also capable of both static tensile, compression tests and quasi-dynamic tests including low-cycle fatigue tests.
