Precision and Robustness for Large Bores
The AC300 is designed for professionals who require accurate measurements over extended dimensional ranges (up to 300 mm). Its rugged construction and the use of treated materials ensure a long operating life, maintaining the precision required for rigorous quality control standards in the workshop.
Technical Features and Benefits
- High Strength Contact Mechanics: Comes with a set of interchangeable extensions featuring chrome steel contact tips, with a hardness of 62/64 HRC to minimize fretting wear.
- Guaranteed Thermal Stability: The chrome-plated rod is equipped with a special heat-insulating handle, essential for protecting the instrument from expansion caused by the heat of the operator's hands during measurement.
- Operational Simplicity: The instrument integrates steel centering brackets that allow automatic positioning on the actual diameter of the hole, reducing the uncertainties of manual surveying.
- Measuring Capability: Covers a wide measuring range from 100 to 300 mm with a maximum depth of 180 mm , making it ideal for engine cylinders, bearing seats and heavy structural components.
Areas of Application
Indispensable in large engine grinding shops, industrial maintenance departments and metrology laboratories where the geometric conformity of the holes is a critical requirement for correct mechanical operation.
