Precision gauge block for calibration labs

The Mitutoyo 611192-541 is a rectangular steel gauge block manufactured to ASME AS-1 grade accuracy. It serves metrology technicians who require traceable dimensional references for calibrating measuring instruments and verifying inspection equipment.

Verify your calibration requirements first

Confirm that AS-1 grade tolerance meets your laboratory uncertainty budget before ordering. The block carries a Certificate of Inspection rather than a long-form calibration certificate, so ensure this documentation level satisfies your quality-system audit requirements.

Replaces worn or lower-grade reference blocks

Upgrade from Grade 0 or Grade B blocks when tighter length tolerance is needed for high-precision setups. The jump is justified when your measurement uncertainty analysis demands the narrower AS-1 tolerance band for critical dimensions.

Questions about this item

What comes with the Mitutoyo 611192-541 gauge block and do I need to buy anything else?

The block is supplied with a Certificate of Inspection. No additional accessories or calibration certificates are included, so any mounting hardware or storage case must be purchased separately.

How do I choose between the available grades or sizes for this 13/64 inch block?

This item is a single AS-1 grade block with a nominal size of .2 in (13/64 in). No other grades or capacities are offered for this part number, so there is no selection to make.

What does the AS-1 tolerance of .0120 in mean when I use the block on a machine?

The length tolerance of .0120 in indicates the maximum permissible deviation from the nominal .2 in size. In practice the block will measure within that range, making it suitable for calibrating inspection tools to ASME AS-1 requirements.
