Precision you can rely on for external measurements. The Insize 3210 Series outside micrometer set delivers 0.001 mm graduation for ultra-fine checks on parts up to 150 mm in length.

• Graduation: 0.001 mm (1 µm) resolution for precise readings on small dimensional changes.
• Measuring Faces: Carbide measuring faces provide exceptional wear resistance for repeatable measurements over time.
• Measurement Range: 0–150 mm external measurement range to cover a broad set of parts and components.
• Calibration Accessories: Supplied with setting standards for quick, reliable calibration (except the 0–25 mm size).
• Series: 3210 Outside Micrometer family designed for durability and enduring accuracy in workshop and shop-floor environments.

This outside micrometer set is built for professionals who need dependable, repeatable measurements in quality control, machining, and precision assembly. The 0.001 mm graduation enables you to detect minute dimensional variations, while carbide faces resist wear to maintain accuracy after many measurement cycles. With included setting standards, you can calibrate quickly on-site, reducing downtime and ensuring consistent results across parts and batches.
