Vernier Caliper – 150mm/6-Inch Stainless Steel Precision Measuring Tool

The Vernier Caliper is a precision measuring instrument designed for accurate dimensional measurements in marine engineering and shipboard maintenance. This robust stainless steel caliper delivers reliable readings of external, internal, and depth measurements with a resolution of 0.02 mm / 0.001 inch. Its hardened jaws and finely machined measuring surfaces ensure repeatable precision, making it an essential tool for ship chandler supplies and onboard repair tasks.

Ideal for engineers, marine surveyors, and shipyard technicians, this caliper features a traditional vernier scale for easy reading, a depth rod for step and slot measurements, and a dial-type adjustment lock to preserve measurements. The corrosion-resistant construction withstands harsh saltwater environments, ensuring long-term durability and consistent performance in coastal and offshore applications.
