50-75mm 2-3" IP65 Waterproof/Dustproof Digital Outside Micrometer - 3108 Series (Insize)

The IP65-rated digital outside micrometer from Insize covers 50–75 mm (2–3") measurements with a rugged, weather-resistant design built for shop floors and service environments. Its dustproof and waterproof protection lets you work confidently around oils, coolants, and dusty conditions while you take quick, precise readings.

Powered by a standard SR44 or LR44 battery, the device features a large digital LCD for fast readings, carbide measuring faces for long life, a spherical anvil for versatile contact, and a simple on/off/set/ABS/INC control. Setting standards are included (except 0-25mm) to help you calibrate quickly and maintain measurement accuracy.

• IP65 protection for tough environments: Keeps dust and water out, so you can measure near coolants and in dirty, fluid-filled workspaces without compromising accuracy or tool life.
• 0.001 mm resolution with ABS/INC: Delivers precise digital readings and lets you switch between absolute and incremental modes for flexible inspection workflows.
• Durable carbide faces, spherical anvil, and ratchet: Wear-resistant measuring faces extend tool life, the spherical anvil handles curved features, and the ratchet ensures consistent, repeatable pressure for reliable results.

This digital outside micrometer helps you speed up setup and inspections while reducing measurement variance. With IP65 protection, it stays dependable in coolant spray and dusty environments, cutting downtime and rework. The 0.001 mm precision supports tight tolerances, while the carbide faces resist wear through busy production runs. Paired with the included setting standards and straightforward ABS/INC operation, it offers fast calibration, repeatable readings, and confidence across manufacturing, maintenance, and QA tasks.
