Each gauge block is calibrated for length on a highly accurate gauge block interferometer (GBI) system.• Available as rectangular gauge blocks in the range 100 to 500 mm.ZERO CERA Blocks• Zero Cera Block is a next-generation gauge block made from a special lightweight ceramic having extremely low thermal expansion (0±0.02×10-6/K (20 ºC)) and exhibiting almost no secular change, both in dimension and coefcient of thermal expansion.• Complementary ultra-low thermal expansion and high specic rigidity (Young's modulus/specic gravity)• Available as rectangular gauge blocks in the range 30 to 1000 mm.For details, please refer to Leaet No. E4334 "Gauge Block with calibrated coefcient of thermal expansion".
