75-100mm/3-4" IP54 Type B Digital Point Micrometer - 3530 Series (Insize)

The Insize 3530 Series Digital Point Micrometer is a precision instrument designed to measure the web thickness of drills, small grooves, and keyways. With a 75–100 mm (3–4") range and 0.001 mm (0.00005") resolution, it delivers fast, repeatable readings in a compact, easy-to-use package.

Built for engineering, manufacturing, and maintenance environments, this micrometer combines durable carbide measuring faces, a reliable ratchet stop, and an IP54 waterproof housing to withstand daily shop wear while maintaining accuracy. It’s suited for technicians who need dependable measurements with minimal setup.

• High-precision 0.001 mm resolution: The digital readout provides readings to 0.001 mm (0.00005"), enabling precise measurement of web thickness on drills, grooves, and keyways, reducing rework and guesswork.
• Rugged carbide faces with ratchet stop: Carbine measuring faces resist wear and corrosion, while the ratchet stop ensures consistent force during measurement for repeatable results across many parts.
• IP54 protection with easy data handling: Sealed housing guards against dust and water spray; user-friendly controls (on/off, set, mm/in, ABS/INC) and optional data output cable (code7302-SPC6) simplify recording and integration into QC workflows; uses LR44 battery with automatic power-off for long life. Range up to 100 mm.

This micrometer helps you speed up setup, improve measurement reliability, and keep precise records, making it a dependable choice for machine shops, engineering labs, and field maintenance alike. The combination of a broad 75–100 mm range, robust build, and data output option supports both hands-on measuring and data-driven quality control.
