High Precision Extensometer Calibrator is the necessary equipment to calibrate the
extensometer, whose accuracy and its application range is equal or superior to similar
calibrate various of extensometers
Using ultra precision micrometer head, high precision and stable performance.
The whole calibrator adopts the modular structure, easy to operate.Suitable for different
range and different environment extensometer’s calibration.
