Digital dial gauge M301.052.3 — 25 mm range, Ø16 mm measuring bridge

The Digital dial gauge M301.052.3 is a workshop-grade measuring instrument designed for comparative and positional checks in mechanical engineering and quality control, combining a compact measuring range with extendable reach for recessed features.

Digital display with ABS/PRESET and mm/inch 25 mm range, 0.01 mm resolution Ø16 mm measuring bridge, 140 mm depth Extensions 10, 20, 40, 70 and 100 mm

Consistent precision for routine quality control

This instrument delivers measured values with a 0.01 mm display step (0.0005 in), providing the resolution expected in standard mechanical workshops. The calibrated digital readout minimises reading errors common with analogue instruments and supports absolute and preset modes for fast setup. As a consequence, inspection cycles become more reliable and traceable, ensuring that batch checks and assembly verifications run with fewer iterations and less downtime. The compact range is ideal for fine adjustment tasks where short-stroke precision is essential.

Reach and adaptability for recessed and deep features

A Ø16 mm measuring bridge and a set of five extensions (10, 20, 40, 70, 100 mm) mean the gauge adapts to components with limited access or deeper bores. The base measuring depth of 140 mm combined with extendable probes allows measurements in pockets or stepped parts without resorting to ad hoc tooling. Extension use preserves the instrument’s alignment and repeatability, so comparative and positional checks remain consistent across different depths — a practical advantage when inspecting stepped housings, recesses or valve seats.

Clear operation that saves time at the bench

Operation is simplified by the digital interface with 0/ON, ABS/PRESET and mm/inch functions, allowing rapid switching between absolute and incremental measurement modes as well as imperial units. The possibility of reversing the measurement direction supports diverse fixturing orientations and comparative measurement routines. At about 0.62 kg the gauge is lightweight enough for handheld use yet solid enough for stable contact, improving throughput during batch inspections or setup processes.

Workshop integration and traceability

Supplied to Werksnorm, the instrument fits routine quality-management workflows and inventory systems; identifiers such as GTIN and eClass facilitate procurement and documentation. The reversible measurement direction and preset capability support comparative checks and go/no-go evaluations without complex additional equipment. Backed by the Metav IndustryLine offering, this digital gauge suits machine shops, maintenance departments and inspection benches where robust, repeatable readings are required for process control and acceptance testing.
