Mitutoyo Steel Gauge Block offers you the following benefits:

Outstanding dimensional stability: Mitutoyo steel gauge blocks are made exclusively from artificially aged material.
High gauge reliability: The gauge blocks can be used as a standard for a long time due to their high dimensional stability.
The maximum permitted length changes to gauge blocks over a year are defined in EN ISO 3650. Mitutoyo high-quality gauge blocks easily meet these and all other requirements.
Steel gauge blocks are excellent for use as a standard because of the low measurement uncertainty that can be achieved when using them.
Mitutoyo steel gauge blocks have top-quality surfaces, guaranteeing high wringing force.

Mitutoyo Ceramic Gauge Block offers you the following benefits:

Due to the ceramic material, these gauge blocks are highly wear-resistant and corrosion-resistant.
CERA blocks feature ten times the abrasion resistance of steel gauge blocks and three times that of hard metal blocks.
Steel and ceramic have similar expansion coefficients which reduce measurement errors that occur due to temperature change.
Non-magnetic: Powders (such as iron grit) will not adhere to surfaces
Clearly visible marking: Black characters on a snow-white surface.
More or less free from dimensional change over time.
Can adhere to steel gauge blocks.
ree from burrs caused by scratches.
