About the Mahr Precimar Length Comparator
Length comparators measure the small difference between a test piece and a known reference (master) length, rather than an absolute dimension — the standard method for verifying gauge blocks and other length standards to sub-micron resolution. Mahr's Precimar range is a long-established name in this category.
A Precimar comparator is typically the centerpiece instrument of a serious calibration lab's gauge block verification workflow, feeding results back into the lab's traceability chain.
