GYB-300CD extensometer calibration instrument
GYB -: The 300CD extensometer calibration instrument consists of a precision differential probe and a measuring bracket. The precision differential probe and support arm are combined in various ways or positions, and are equipped with extended column attachments, as well as various forms of separated samples such as cylinders, plates, and blades. According to the requirements of the JJG762-2007 extensometer calibration regulation, it is used to calibrate various types of extensometers
