The 125-150 5-6" IP65 Digital Outside Micrometer from Insize, part of the 3101 Series, is designed for precise exterior measurements in demanding shop environments. With IP65 waterproof protection, carbide measuring faces, and a bright digital readout, it delivers fast, repeatable results even near fluids and coolant sprays. Supplied with a spherical anvil and standard-setting references (except 0-25mm/0-1"), it’s ready to handle routine gauging tasks out on the floor or in the maintenance shop.
Designed for reliability and ease of use, this micrometer combines a durable carbide face with a ratchet for consistent pressure and long tool life. It offers a clear 0.001 mm / 0.00005" resolution and convenient controls for on/off, zero, mm/inch, ABS/INC, and data output, all powered by a common SR44 or LR44 battery. Optional accessories include a foot switch for data transfer (7304-2) and a data output cable (7302-SPC6), making it easy to integrate into SPC workflows. The measurement range extends up to 300 mm (12"), enabling larger exterior checks without changing tools.
- IP65 waterproof robustness: Sealed against water, coolant, and dust so you can measure near machines and during washdowns without worry, minimizing downtime and maintenance.
- High-precision carbide measuring faces: Durable, wear-resistant surfaces paired with a ratchet for repeatable, accurate readings to 0.001 mm / 0.00005".
- Built-in data output & versatile setup: Digital readout with mm/inch, ABS/INC, and data transfer support; includes spherical anvil and optional foot switch (7304-2) or data cable (7302-SPC6) for easy integration into measurement systems.
This micrometer helps you streamline exterior gauging, improve measurement consistency, and document results with confidence. Its rugged build, precise readings, and data-connectivity options support faster inspections, reduced rework, and better overall quality in manufacturing and maintenance environments.
