Applications:

Application
 The single fibers are stretched to break on a constant elongation extensometer (CRE) under specified conditions. The values of tensile strength, elongation at break, elongation strength, and initial modulus of the specimen obtained from the load-elongation curve or the data display acquisition system are suitable for the tensile test of chemical fiber and natural fiber Stretch performance test.

Product Information:

 In the tensile test, the measured fiber is sandwiched between the upper holder and the lower holder. According to the panel operation instruction, the monitoring and control program generates the step pulse by the pulse generator , moves up and down the holder by the stepping motor and the transmission mechanism, and reads the number of the step pulse from the reversible counter to complete the elongation measurement.
The load of the measured fiber is generated by the transmission mechanism on the load force sensor. The output signal is passed through the amplifier and the analog-to-digital converter, and the load measurement is completed by reading the conversion result from the monitoring and control program.

Accessories
 The device can indicate or record the load applied to the specimen and the corresponding elongation value; (Force sensor)
The device can make load-elongation curve; (Integrated software)
The gripper suitably holds a single fiber at the desired nominal gauge length; (Manual, pneumatic and electric. The pneumatic gripper avoids the influence of the measurement of the force sensor and also reduces the degree of damage to the special brittle material during the clamping process.)
The device has a different stretching speed; (Stepper motor)
The device is used to wet the fibers in a wet state experiment so that the fibers are immersed during the test without affecting the test results; (Containers)
The device is used to precisely calibrate the instrument.
