Features

• Zero-Setting Function: Unlike fixed-scale manual calipers, this model allows the vernier plate to be adjusted, enabling the user to set a "Zero" point at any part of the beam—ideal for go/no-go gauging or measuring deviations.
• Long-Reach Jaws: Equipped with jaws, providing significantly more depth reach than standard jaws
• Solid Type Construction: The main beam is made of a single piece of hardened Stainless Steel, ensuring maximum rigidity at its full extension.
• Fine Adjustment: Equipped with a secondary sliding block and thumbwheel, which is mandatory for precisely positioning the jaws on a workpiece.

Applications

• Comparative Gauging: Setting the "Zero" to a master part to quickly check if subsequent parts are within tolerance (plus/minus deviation)
• Large Diameter Pipes: The 90 mm jaws are designed to bridge over the curve of large industrial piping for accurate diameter checks.
• Heavy Fabrication: Measuring large structural plates, bulky castings, and oversized engine components.
• Foundry Use: Ideal for raw castings where the deep reach is needed to bypass surface irregularities.
