Mitutoyo 530-101 Vernier Calipers | Stainless Steel | OD/ID/Depth/Step | 0–150 mm Range | ±0.05 mm

Precision you can rely on

The Mitutoyo 530-101 Vernier Calipers are designed for precise measurement across a variety of tasks, from hobby projects to professional workshops. Built from hardened stainless steel with a satin chrome finish, this caliper combines durability with a smooth, confident glide that stays readable even after routine use. The combination of robust materials and thoughtful design helps keep graduations clear and legible over time, making it a reliable tool for everyday measurement work.

What you can measure with confidence

This caliper supports outside dimensions (OD) and inside dimensions (ID), as well as step measurements. When equipped with an optional depth bar, it can also measure depth, and the generous 40 mm jaw depth makes it easier to capture larger parts without losing control over the reading. The tool covers a practical range from 0 to 150 mm, with a resolution of 0.05 mm and an accuracy of ±0.05 mm, giving you a precise readout for a wide array of components.

• Outside and inside diameter checks with clear graduations
• Depth and step measurements for layered features
• Wide 40 mm jaw depth for larger parts

Designed for readability and durability

The vernier scale adopts a modest 14 degree face angle, which aids visibility and helps minimize reading errors caused by parallax. Raised sliding surfaces guard the scale from wear during frequent use, helping preserve the accuracy of measurements over time. A satin chrome finish not only looks refined but also enhances corrosion resistance and handling comfort.

• Parallax-reducing vernier angle for easier reads
• Raised sliding surfaces protect graduations
• Hardened stainless steel with satin chrome for durability

Standards, use cases, and care tips

Built to meet Federal Accuracy Specifications GGG-C-111B, the Mitutoyo 530-101 aligns with recognized industry expectations for precision tools. This makes it suitable for metalworking, woodworking, and DIY projects where dependable measurements matter. For best results, clean and dry the tool after use, store it with jaws closed, and calibrate against a known standard if traceable accuracy is required.

Summary of benefits

• High strength and long life with hardened stainless steel
