Model WAW-2000E Computer Control Electro-Hydraulic Servo
Universal Testing Machine

Functions & Applications:
Model WAW-2000E Computer Control Electro-Hydraulic Servo Universal Testing Machine is
suitable to test various metallic & non-metallic materials for tension, compression, bending and
shearing strength. It can be capable of testing the characters of materials on physical & technology
properties. It is simple, easy to operate and widely used in works, laboratories and high schools for
material properties research and quality control.
Equipped with the computer & Software & printer, it can display, record, process and print the test
results, and control test procedures as the set program and can draw test curves automatically in
real time.
The machine complies with ASTM E4, ISO7500-1, ISO6892, ISO379,
ASTM D76, JISZ2841 standards.
