VE seriesVideo extensometer Features:

• Rich application tools: point, line, torsion line, bending line, extreme line, cross line, line strain distribution, data post-processing, crack length measurement, full-field DIC;

• Non-contact measurement, without applying any external force to the tested sample, to ensure the rigor of the test;

• Lateral measurement: can be arbitrarily set transverse width line, automatic edge detection, high-precision measurement of transverse strain;

• The whole process is tracked to the specimen fracture, and there is no need to worry about the fracture of the specimen causing the damage of the extensor, which fully ensures the safety of the test operator;

• Before the test, there is no need to do any treatment on the surface of the sample (the sample with clear texture), and the test can be started after the sample is loaded.

• The scale distance of the extensometer is arbitrarily set within the field of view, and the placement position of the extensometer on the sample is arbitrarily set;

• It is not necessary to mark the distance point of the sample before the test, and it is not necessary to splice the broken sample after the break, and directly calculate the total elongation at break and the elongation after the break.

• Using optical principle, without any mechanical loss, once the calibration accuracy is unchanged for life;

• Fast positioning, fixed working distance, standard laser assisted alignment system;

• Light source supports automatic switching to reduce light pollution;(The light source is automatically turned on at the beginning of measurement and automatically turned off at the end of measurement)。

  
  

Note: Can be adapted to high temperature furnace, high and low temperature environment chamber, with testing machine to test the elongation at break, stress and strain, elastic modulus and other parameters。
