Dial Calipers The Dial Caliper is a precision measuring instrument designed for accurate outside diameter (OD), inside diameter (ID), depth, and step measurements. Equipped with a high-visibility yellow dial, the caliper offers easy reading and enhanced measurement visibility in workshop and industrial environments. The precision rack-and-pinion mechanism converts slider movement into dial readings, providing smooth operation and reliable measurement accuracy. Its shock-proof movement protects the internal mechanism from accidental impacts, while the covered rack design prevents dust and debris from entering the gear system, ensuring long-term durability and consistent performance. Manufactured from high-quality stainless steel, the Dial Caliper is widely used in manufacturing, machining, automotive industries, tool rooms, quality control departments, fabrication workshops, and metrology laboratories.
