Mahr Metrology - Precimar 826 PC Gage Block Comparators

The 826 PC gage block measuring instrument is quick, reliable and highly accurate. An open and extremely rigid L-shaped stand forms the base for the two counteracting precision measuring probes and the measuring table.

• Rigid cast stand for temperature stability and heat resistance
• Fast adjustment of vertical slide with top probe
• Highly ergonomic, user friendly one-handed operation to position the gage blocks under the measuring probe
• Precision adjustment via torsionally rigid parallelogram springs
• Electropneumatic lifting of measuring probes
• Precision ball bearing guides for smooth manipulator actuation
• No influence on measurement from hand force
• Round carbide precision support pins make it easy to move the gage blocks on the measuring table
• Set value linked to the stored actual deviation of the reference gage block, avoiding the need for zero point setting

• Flattening correction
• Correction of differing coefficients of expansion
• Mean value generation
