Professional Heavy Duty Vernier Caliper with Step/Jaw Extension for Large-Scale Precision

Our H-150B series represents the pinnacle of industrial-grade measuring tools, designed for machinists and engineers who work on large, complex components. This isn’t just a caliper; it’s a multi-function precision instrument built for challenges that standard calipers can’t handle. The integrated step dimension and long jaw design allows you to accurately measure external dimensions (OD), internal dimensions (ID), and step dimensions in hard-to-reach areas of massive parts, from engine blocks to structural fabrications.

Crafted from hardened stainless steel, its massive beam resists deflection under its own weight, ensuring unwavering accuracy across its entire measuring range. The ultra-clear vernier scale provides multiple resolution choices (0.05mm, 0.02mm, and 1/128″) to meet both metric and imperial blueprint specifications.

Key Features & Technical Specifications:

• Unmatched Capacity & Range: Choose from 8 precise sizes to fit your project needs: 0-500mm, 0-600mm, 0-800mm, 0-1000mm, 0-1500mm, 0-2000mm, 0-2500mm, and 0-3000mm.

• Step & Long Jaw Measurement: The defining feature. Equipped with robust normal jaws and specialized extended jaws (up to 400mm) for measuring deep recesses, internal grooves, and step heights that are impossible to reach with standard calipers.

• Multi-Resolution Precision: Achieve exceptional accuracy with your choice of resolution: 0.05mm, 0.02mm, or 1/128 inch, all on a single, precision-etched scale.

• Industrial-Grade Durability: Forged from hardened, corrosion-resistant stainless steel to withstand the rigors of daily use in machine shops and on the factory floor.

• Ergonomic & Secure Grip: Designed for control and comfort during extended use, even on the largest sizes.
