1、 Product introduction of extensometer:

thatHigh temperature axial extensometerSimultaneously measure axial and torsional strains at high temperatures. Suitable for material testing furnaces or induction heating to1200Degree or1600°C（2900°F）The environment. Circular specimens tested in a biaxial testing machine capable of withstanding both axial and torsional loads simultaneously. Can be displaced bidirectionally on two axes and can be used for up to10 HzThe fatigue test of strain control is carried out at a frequency of, and the high-temperature extensometer is firmly installed on the load frame, and a sliding installation method is used to make contact between the extensometer and the sample.
