The HR Series Micrometer Heads 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.
All HR series micrometers have the same 9.5-mm mounting interface making them both interchangeable with other micrometers and compatible with the Newport stages listed below.
HR Series Lockable High-Resolution Micrometer Heads have 0.25 mm pitch threads (over 100 TPI), providing twice the sensitivity of standard SM Series. These fine threads allow 0.5 µm sensitivity with direct position readout in 5 µm graduations. They are recommended for applications requiring sensitive positioning, as well as accurate position readout.
