产品详情
一、高温引伸计产品简介：
1600度/1700度高温引伸计配合高温拉伸试验机用于各种材料高温力学的应变测试。可配FLWK1200度高温炉\1600度高温炉\1700度高温炉\真空高温炉等使用。The MFHT 5 has been conceived as a highly accurate, sturdy measuring device for hot tensile tests in a folding furnace. 2 initial gauge lengths are offered as standard. Le 25 mm and Le 50 mm can be adjusted quickly and fast by turning over the feeler arms. Due to its extremely low activating force, the unit enables the testing of highly sensitive samples which permit only the lowest surface pressures.
