一、高溫引伸計產(chǎn)品簡介：

1600度/1700度高溫引伸計配合高溫拉伸試驗機用于各種材料高溫力學(xué)的應(yīng)變測試?？膳銯LWK1200度高溫爐\1600度高溫爐\1700度高溫爐\真空高溫爐等使用。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.
