Mitutoyo 329-250-30 : Digital Depth Micrometer 0-150mm
Part No. 329-250-30 | Mitutoyo Series 329
Product Description
The Mitutoyo 329-250-30 is a Digimatic depth micrometer for measuring holes, slots, steps and recesses across a 0–150 mm range. Its digital LCD provides 0.001 mm resolution, while the micrometer head has ±3 µm accuracy according to Mitutoyo specification.
Six interchangeable ø4 mm rods cover the measuring range in 25 mm increments. The rods can be adjusted for calibration and wear compensation and are secured with a rod clamp during measurement. A ratchet stop helps provide consistent measuring force for repeatable readings.
The hardened, ground and micro-lapped 101.6 × 16 mm base provides a stable reference surface, with 2 µm base flatness. Digimatic functions include origin setting, zero setting, data hold, function lock and presets for convenient inspection workflows.
For inspection records and digital data collection, the SPC data output can send measurements to a compatible PC or data logger using the appropriate Mitutoyo SPC cable.
For a longer measuring range, see the Mitutoyo 329-350-30 with a 0–6" range. For a mechanical depth micrometer, see the Mitutoyo 129-116.
