Precision-engineered universal height master with 0.00001\” graduation, 12.2\” range, and staggered 1\” block step—ideal for high-accuracy dimensional calibration.
Mitutoyo 515-311 Universal Height Master, Range 0.2 – 12.2\”, Graduation 0.00001\”, Block Step 1\” Staggered.
The Mitutoyo 515-311 Universal Height Master is a high-precision dimensional calibration standard, designed for laboratories and manufacturing environments that require traceable and repeatable height measurements. Featuring a measuring range of 0.2 to 12.2 inches, a fine graduation of 0.00001\”, and 1\” staggered block steps, this tool ensures ultra-accurate referencing in metrology setups.
With dual measuring faces at the same level (one upward, one downward), the staggered block arrangement improves ease-of-use in both manual and automated systems. Whether you\’re inspecting bore gages or calibrating height gages, this universal height master supports consistent measurement fidelity.
