The MITUTOYO 505-730 Dial Caliper (0–150mm) is a high-precision analog measuring tool designed for accurate and smooth measurement in machining, engineering, and industrial applications.
This caliper offers a measurement range of 0–150mm (6 inch) with 0.02mm graduation, ensuring reliable and repeatable readings. It features a rack-and-pinion dial mechanism, allowing quick and easy measurement reading without batteries.
The large dial face improves readability, while the ultra-smooth sliding movement enhances user control and precision. The tool is built from hardened stainless steel, providing durability and resistance to wear in demanding workshop environments.
Equipped with a lock screw, it allows measurements to be securely held. The caliper supports four-way measurement—outside (OD), inside (ID), depth, and step—making it a versatile all-in-one measuring solution.
