Digimatic Inside Knife Edge Point Type Calipers The Digimatic Inside Knife Edge Point Type Caliper is a precision digital measuring instrument specifically designed for accurate inside groove measurements, internal recess inspection, slot width measurement, and other hard-to-reach internal dimensions. The knife-edge measuring jaws provide excellent access to narrow grooves and recessed areas where standard calipers cannot measure effectively. Manufactured from high-quality stainless steel, the caliper offers durability, corrosion resistance, and long service life. The digital display provides fast and error-free readings, while data output capability enables integration with quality control and measurement recording systems. With inch/mm conversion and zero-setting functionality, it is an ideal tool for manufacturing, machining, automotive, aerospace, tooling, and metrology applications.
