1. introduction
The hydraulic universal testing machine use oil cylinder
down-setting method and four column double screw structure,It is
major applied to do stretch, compression, bend and shear test for
metal, non-metal material.It is suitable for
metallurgy,construction,light industry, aviation,
aerospace,material,universities and colleges, R&D institution
etc, field,The test peration and data processing are corresponded
with the related requirements in GB/T 228-2002/2010.

3. features
This universal testing machine can program the crosshead speed or
conduct cyclical testing, allow testing at a constant force,
testing at constant deformation, testing at constant displacement,
etc.
This testing machine can equip with extensometers to measure the
extension or deformation.
According to test requirement for temperature, humidity, pressure,
etc, special device, such as environmental chamber can be placed
around the test specimen to do test in certain temperature,
humidity or pressure.
Matched with various test fixture, like peal, puncture, tear,
pneumatic grip, belt tension, etc. This UTM can be used to metal,
non-metal, composite materials like rubber, steel wire, plastic,
seat belt, textile character test.
Protecting functions of over load, over current, over voltage,
crosshead limit moving space protection, auto stop at break.
4. software introduction
- Easy to control and friendly interface
windows based interface, easy and fast to reach different
functions, suitable for most of operators using habits. Integrated
all common operation functions, like specimen information input,
specimen choosing, curve plotting, data display, data process, data
analysis, test operation etc., easy and convenient to operate.
- Full digital display and computer control
Adopting remote controller, fast response and reliable to parameter
gathering. Realize digital adjustment and zeroing of load,
deformation and displacement as well as PID parameter adjusting.
- Different control mode & speed setting
- Programmable control mode
Users can program test mode according to their own requirements.
- Load holding facility for a specific period:
