Using cutting-edge grating sensors and temperature-adjusted scales, high precision digital calipers offer accuracy levels of 0,0005mm. The models with Flower Pattern Granite Base (thermal expansion ≤0.8×10⁻⁶/°C) are stable in metrology labs and the caliper tipped jaws made of carbide (1400HV) are wear resistant in production settings. These instruments are calibrating devices for other measuring devices offered under the ISO17025 guidelines, measuring aerospace fasteners and optical components serves as precision standards.
