Precimar 826 PC Gage Block Measuring Unit Description The 826 PC gage block measuring unit is fast reliable and extremely precise. In comparative measurement it achieves a reproducibility of 0.01 m. An open and extremely rigid L-shaped stand forms the basis for the two opposing high-precision probes and the perfectly level measuring table. Work is made easy thanks to straightforward one-handed operation for manipulating reference and test gage blocks on the measuring table. The open design allows visual contact during testing. The user is able to view the measuring process at all times which helps to ensure a unique level of process reliability. Two professional measuring and evaluation programs (software) meet all the needs of internal gageblock tests calibration laboratories and gageblock manufacturers. Features Rigid cast-iron stand ensures a stable temperature and insensitivity to heat Easily adjustable vertical slide with upper probe Very ergonomic and convenient one-handed operation for positioning the gage block under the probe Fine adjustment via rigidly connected parallelogram springs Electropneumatic lifting of the probes Extremely smooth manipulator operation thanks to high-precision ball bushings Measurement not influenced by manual force applied Gage blocks easy to move on the measuring table thanks to round hardened high-precision support pins No zero point setting required since the set value is offset by the stored actual allowance of the respective reference gage block Very effective protection from heat due to an acrylic glass screen along the sides of the unit Flattening correction Correction of differing coefficients of thermal expansion Calculation of mean values Accessories QMSOFT QM-Block for calibration and management of gage blocks and gage block sets The evaluation software operable under Microsoft Windows 7 Very effective protection from heat due to an acrylic glass screen along the sides of the unit Lifting device 826 Va HS for the fast and quiet pneumatic lifting of the inductive probes via footswitch. Temperature compensation Wooden tongs pneumatic gage block lifter optical flat surface thermometer The 826 enables quick and straightforward high-precision testing of European and US gage blocks up to 170 mm (6.69 in) long in accordance with ISO 3650.
