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 ( 1 in). 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 provides 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 gage block tests calibration laboratories and gage block manufacturers. Features Rigid cast-iron stand ensures a stable temperature Vertical slide with upper probe easily adjustable Very ergonomic and convenient one-handed operation for positioning the gage blocks 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 because 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 front and sides of the unit (available as an option) Flattening correction Correction of differing coefficients of thermal expansion Calculation of mean values Two measuring and evaluation programs Calibration and data management or additionally with customer management gage block storage management and multi-test-unit management Accessories QM-Block calibration software for calibration and data management of gage blocks and sets of gage blocks The evaluation software runs under Windows NT 2000 XP The 826 enables quick and straightforward high-precision testing of rectangular and square gage blocks in both inch and metric up to 170 mm (6.69 in) long in accordance with ISO 3650.
