INSIZE Non Magnetic Outside Micrometer with Carbide Faces

SKU 3231-25A
$1,289.54

Precision You Can Trust With the INSIZE Non Magnetic Micrometer

Working with magnetic materials and tired of readings pulled off by stray magnetic fields? This is where a non magnetic micrometer earns its place on your bench. Built with non magnetic carbide measuring faces and a ratchet stop for consistent contact pressure, you get clean, repeatable measurements every time your work involves ferrous or magnetized parts.

Range (Size) 0–25 mm 25–50 mm 50–75 mm 75–100 mm
Accuracy ±4 μm ±4 μm ±5 μm ±5 μm
  • Magnetic material ready: Built to measure ferrous or magnetized parts without interference from stray fields.
  • Non magnetic carbide faces: Wear-resistant contact points that stay free of magnetic pull.
  • Ratchet stop: Applies even measuring force for repeatable readings, pass after pass.
  • Range options: Available in 0–25 mm, 25–50 mm, 50–75 mm, and 75–100 mm to match your parts.
  • Accuracy: ±4 μm on smaller ranges, ±5 μm on larger ranges.
  • Graduation: 0.01 mm divisions on every model for clear, fine reading.
  • Series: INSIZE Code 3231 outside micrometer line.

Built for Magnetic Materials Without the Interference

Benefit icons showing why the INSIZE Non Magnetic Precision Micrometer resists magnetic pull on ferrous parts

Standard micrometers can behave unpredictably around magnetic materials, where magnetized parts drag on the spindle or skew your contact. This tool sidesteps that problem entirely.

  • Suitable for magnetic materials that would throw off ordinary tools
  • Non magnetic carbide measuring faces resist wear while staying free of magnetic pull
  • Consistent contact so your readings reflect the part, not the field around it

Why the INSIZE Outside Non Magnetic Micrometer Keeps Readings Repeatable

Icons explaining how the INSIZE Non Magnetic Outside Micrometer delivers repeatable readings with a ratchet stop

Uneven hand pressure is one of the biggest sources of measurement error. The ratchet stop solves this by applying the same force each time you close the faces on your workpiece.

  • Uniform measuring force for repeatable results across operators
  • 0.01 mm graduation for fine, readable increments
  • Carbide faces hold their geometry through heavy use

Choose the Right INSIZE Non Magnetic Precision Micrometer for Your Range

Grid of four range and accuracy options for the INSIZE Non Magnetic Precision Micrometer from 0 to 100 mm

Four size options cover measuring needs from small parts up to larger components, so you can match the tool to the job.

  • Range: 0–25 mm, 25–50 mm, 50–75 mm, or 75–100 mm
  • Accuracy: ±4 μm on the 0–25 mm and 25–50 mm models, ±5 μm on the 50–75 mm and 75–100 mm models

Accurate Measurement From the INSIZE Non Magnetic Outside Micrometer

Accuracy stat grid for the INSIZE Outside Non Magnetic Micrometer showing 4 and 5 micron tolerances and graduation

Every model in the Code 3231 series holds tight tolerances so you can rely on the numbers you read.

  • ±4 μm accuracy on smaller ranges for close work
  • ±5 μm accuracy on larger ranges where reach matters
  • Consistent 0.01 mm graduation across all four sizes

Machinists Reach For the Non Magnetic Outside Micrometer INSIZE

From inspection stations to production floors, this design brings together the features that matter when magnetic parts are in play.

  • Wear-resistant carbide faces built to last
  • Ratchet stop for even, controlled contact
  • Sizing options that grow with your workpieces

Fine Increments With the INSIZE Non Magnetic Micrometer Gauge

Spec highlight showing 0.01 mm fine graduation and carbide faces of the INSIZE Non Magnetic Outside Micrometer

The 0.01 mm graduation gives you the detail you need without straining to read the scale. Combined with the ratchet stop, you get clear, dependable measurements on every pass.

  • Readable 0.01 mm divisions on all models
  • Carbide measuring faces that stay true over time
  • Designed specifically for magnetic material measurement
