The Digitronic digital caliper with long upper internal jaws is designed for precise measurement of grooves, seats, shoulders and internal diameters that are difficult to access with standard jaws. The special configuration of the long and slim upper jaws allows deep internal measurements while maintaining stable contact and consistent alignment during operation.

Made of hardened stainless steel, it ensures rigidity, smooth slider movement and durability under typical workshop conditions. The 9.5 mm high-contrast LCD display provides clear and immediate readability even in low-light environments.

The electronic module includes all essential professional measuring functions: ON/OFF, auto OFF, origin, ABS/INC, mm/inch conversion and preset.
This model features a 0–150 mm measuring range, 0.01 mm resolution and ±0.04 mm accuracy, making it suitable for high-quality dimensional inspections.

Equipped with a 3.8 × 1.4 mm depth rod, it is ideal for internal measurements and geometric verification in production and inspection departments.
Supplied complete with protective case and SR44 battery.
