Product introduction
ETT-C is a microcomputer-controlled electronic universal testing machine designed for mechanical property tests including tensile strength, fixed elongation, elongation at break and yield strength. The frame and accessories are engineered for easy operation and stable performance. The system uses a servo motor driven by an AC speed-control unit and a high-precision ball-screw pair to drive the crosshead over a large travel distance.

Main functional and software features
The machine integrates an AC speed control with a synchronous toothed-belt deceleration system and precision ball screws. PC-based control software (Windows) with virtual-instrument display shows test force, peak force, crosshead displacement, specimen deformation and test curves. A dual-channel full-digital programmable amplifier provides zero adjustment, gain adjustment and automatic calibration without analog potentiometers, enabling simple and reliable control.

Applications

• Tensile testing of metals and non-metals
• Measurement of elongation, tensile strength and yield strength
