Mahr Federal offers inspection and recalibration services for dimensional standards, including gage blocks, master rings, discs, plugs and balls and cylindrical form and precision reference specimens and surface roughness standards, as well as for a range of gages. Quality of these services is ensured by the Mahr Federal metrology lab, which realizes high accuracy measurements with uncertainty as low as 0.06 microns or 2.3 microinches, on gage blocks.

 

Unlike most metrology labs, Mahr Federal's Precision Measurement Center is isolated from the surrounding structure, resting on a 5-foot thick concrete slab that weighs almost 375 tons and is supported by three, 30-foot tubular steel columns that rest on vibrationally stable bedrock. This isolates measurement equipment from external vibrations that can cause inaccuracies.

 

Air and atmosphere are also tightly controlled in the Precision Measurement Center. An air conditioning, circulating and filtration system maintains the temperature, replacing itself every half-minute, eliminating stratification, controlling dust and providing a barrier of clean air between sensitive gages and technicians.
