The 0-25mm (0-1") IP65 Digital Outside Micrometer from Insize 3101 Series is built for precision in tough workshop environments. It’s ideal for machinists, quality inspectors, and maintenance technicians who need fast, reliable outside measurements around fluids and coolants.

  • IP65 waterproof housing: Protects the instrument from water, dust, and coolant exposure so you can gauge in washdown zones and wet work areas without removing the tool.
  • Resolution: 0.001 mm / 0.00005 inches for precise tolerance checks and fine-detail measurements.
  • Carbide measuring faces: Durable, wear-resistant surfaces that stand up to frequent use and maintain accuracy over time.
  • Spherical anvil included: Enhances accuracy when measuring curved exterior surfaces and features.
  • Electronic functions: Simple on/off, zero, mm/inch toggle, ABS/INC mode, and direct data output for streamlined gauging.
  • Power and durability: Powered by SR44 or LR44 batteries, offering convenient replacements in the field.
  • Data output: Built-in data logging capability with optional accessories to transfer measurements for digital records (7302-SPC6 data cable; 7304-2 foot switch).
  • Measurement range: 0–25 mm (0–1"); setting standards included to speed setup and zeroing, except for the 0–25 mm / 0–1" range.
  • Accessories: Optional data-transfer and extension options to fit your workflow and measurement needs.

The digital readout delivers quick, parallax-free results, helping you verify part diameters, spacers, and OD features with confidence. The rugged IP65 seal and carbide faces make this micrometer reliable in production lines where fluids and debris are common, reducing downtime and rework. The spherical anvil supports accurate readings on curved surfaces, while the data output capability and compatible accessories integrate smoothly with SPC and data-collection processes, ensuring you can maintain traceability and consistency across inspections.
