The Insize 3532 Digital Blade Micrometer is a precision instrument designed for measuring groove diameters on shafts and keyways with fast, repeatable readings. Built for machinists, toolmakers, and quality-control labs, it pairs a compact blade with a clear digital display for dependable performance in tight tolerances.

• Range: 0–25 mm / 0–1 in (with extended data-output versions up to 100 mm available).
• Resolution: 0.001 mm / 0.00005"
• Non-rotating spindle: prevents drift and ensures consistent measurements over repeated use.
• Digital display: easy-to-read LCD readout with seamless mm/in conversion.
• Controls: on/off, set (zero), mm/in, ABS/INC, and data output for flexible operation.
• Power: LR44 battery with automatic power-off to extend battery life.
• Measurement feel: ratchet stop provides steady, repeatable contact pressure for reliable results.
• Accessories: supplied with setting standards (except the 0–25 mm / 0–1 in range); optional data output cable CODE7302-SPC6 for data capture.
• Applications: ideal for accurately determining groove diameters on shafts and keyways in manufacturing and maintenance environments.

This digital blade micrometer translates precise tolerances into actionable data. The combination of a compact blade, a stable non-rotating spindle, and a bright, straightforward readout minimizes measurement ambiguity, helping you reduce rework and ensure consistent part fits. With metric/implied-inch conversion at your fingertips and optional data output for traceable records, it fits seamlessly into modern QC workflows, shop floors, and engineering labs where precision matters most.
