0-150mm Digital Outside Micrometer Set - 3109 Series

The 0-150mm Digital Outside Micrometer Set (3109 Series) is a precision measurement tool designed for machinists, engineers, and quality-control professionals who need fast, accurate outside dimensions from 0 to 150 mm. With a digital readout and durable carbide faces, this set delivers reliable performance in busy workshops.

• Measurement range: 0–150 mm (0–6") to cover common outside dimensions in machining and inspection tasks.
• High-resolution readout: 0.001 mm (0.00005") increment for detailed, repeatable measurements.
• Carbide measuring faces: wear-resistant surfaces that maintain accuracy over time in practical use.
• Digital features: simple on/off control, set function, and a convenient mm/inch toggle for metric or imperial workflows.
• ABS/INC mode: switch between absolute and incremental measurement to suit calibration and recurring measurement needs.
• Power and convenience: LR44 battery with automatic power-off helps conserve energy between uses.
• Included standards: supplied with setting standards to enable quick and reliable calibration checks.
• Protective case: compact, durable case for safe storage and easy transport between workstations.

Designed for accuracy in everyday tooling and fabrication tasks, this digital outside micrometer helps you verify shaft diameters, bearing housings, snap fits, and step diameters with confidence. The digital readout reduces interpretation errors, while the carbide faces withstand frequent use in metalworking environments. With metric and imperial options, ABS/INC calibration, and a ready-to-use set of standards, it’s an efficient, reliable choice for precise measurement during setup, inspection, and QC workflows. The included case keeps the set organized and ready for on-site or shop-floor measuring sessions.
