The HR-6 Lockable High-Resolution Micrometers has 0.25 mm pitch threads (over 100 TPI), providing twice the sensitivity of standard SM Series Micrometers. These fine threads allow 0.5 μm sensitivity with direct position readout in 5 μm graduations. The HR-6 is recommended for applications requiring sensitive 6 mm positioning, as well as accurate position readout. The HR Series Micrometers have a novel thumbscrew locking mechanism that clamps a non-threaded portion of the screw from all sides. This stress-balanced design secures the position with negligible displacement during locking.


HR-6可锁定的高分辨率千分尺具有0.25毫米间距的螺纹(超过100 TPI),提供了标准SM系列千分尺两倍的灵敏度。这些细线允许0.5μm灵敏度直接读出位置5μm毕业典礼。HR-6推荐用于需要灵敏的6毫米定位和精确的位置读数的应用。HR系列千分尺具有新颖的拇指螺杆锁紧机构,可从四面夹持螺杆的非螺纹部分。这种应力平衡的设计确保了锁定时的位置,位移可以忽略不计。
