The Digitronic special-execution digital calipers for external grooves with flat contacts are designed for accurate measurement of external grooves and slots on shafts and cylindrical components. The inward-facing jaws rest securely on the surfaces to be inspected, allowing precise determination of groove width and position, even near shoulders or small radii.

The sliding caliper body with a 9.5 mm high-contrast LCD display ensures clear, immediate reading. The electronic unit provides all essential functions for professional use: ON/OFF, auto OFF, origin, mm/inch conversion and preset, which allows a reference value to be set and speeds up repetitive measurements.

Accuracy is defined by a dedicated internal standard, with the corresponding values shown in the technical table, while the robust mechanical design guarantees long-term stability and metrological reliability. The calipers are supplied complete with a protective case and battery, ready for use in workshops, metrology labs and dimensional inspection of components with external grooves.
