Accurate results where small tolerances matter

This instrument delivers 0.02 mm accuracy on a 20 mm measuring range, making it suitable for fine mechanical and small-component inspection. The digital display with a 0.01 mm resolution provides an immediate numeric result, reducing reading errors compared with analogue dials. The Ø1.5 mm measuring pin is engineered to enter narrow bores reliably; its slim profile minimises contact area and helps maintain repeatable measurements. For quality-controlled production, this combination of compact range and fine accuracy shortens inspection cycles while keeping measurement uncertainty low.

Faster routine checks and fewer handling errors

The preset function and reversible measuring direction simplify repetitive tasks: zero can be set quickly and direction inverted to match workpiece orientation, which accelerates batch testing and reduces handling mistakes. A 25 mm measuring stop provides a positive mechanical reference for consistent placement against shoulders and countersinks. The instrument’s compact form and a net weight of 0.62 kg support comfortable single‑hand operation, lowering operator fatigue during repeated checks and improving throughput on the shop floor.

Designed for small bores and everyday workshop use

Classified in the micro range (max. 10–100 mm), this depth gauge is aimed at precision tasks on small components—ideal for toolmaking, watchmaking, precision assemblies and inspection of mating features. The slender probe and short measuring span make it straightforward to use in confined spaces where full-length depth gauges are impractical. The clear numeric readout and preset capability mean less interpretation and faster decision-making during first-article inspections and routine quality checks.

Practical advantages for production and inspection

The gauge is fitted with a purpose-designed measuring insert (Ø1.5 mm × 20 mm) that is durable and suited to repeated entry into small holes. The device’s digital measurement eliminates parallax and non-linearity typical of analogue instruments, while the reversible measurement direction adapts to different fixturing and measurement approaches. Together, these features support a lean inspection routine that preserves traceability and helps maintain consistent quality across production batches.
