Introduction:
The electronic extensometers made according to resistance strain principle, and have YYU, YYJ two series. It has legerity structure, good stability and easy to operate. Have became the essential sensor for strain automatic testing and been widely used in various academies, scientific research institutes, factories, laboratories.
