The high accuracy of TESA’s gauge blocks is the result of years of experience in producing
and making use of these products.
• Use of high quality raw materials and appropriate heat treatment, thus guaranteeing
a durable shape and dimensional stability of the gauge blocks over years.
• Very low deviations in flatness and parallelism of the measuring faces, resulting in
highly accurate gauges.
• Unique flat lapping polish as well as edge rounding techniques, leading to superior
wringability.
• Proper serial number marked on each gauge block.
