Description

This H-152 series heavy-duty vernier caliper is a professional large-scale dimensional measuring tool built for heavy industrial inspection scenarios. It solves the rigidity and accuracy limitations of standard small-size Calipers when measuring oversized workpieces, delivering stable, repeatable dimensional readings across extended measuring strokes. With optional extended jaws and two frame structure options, it adapts to a wide range of applications from large machined parts and welded structures to ship components and construction equipment.
  1. 8 Large Measuring Ranges with Industrial Stainless Steel Build
    Eight standard models cover measuring capacities from 500mm to 3000mm, accommodating almost all large workpiece inspection requirements in heavy industry. Machined from high-grade hardened stainless steel with anti-corrosion surface treatment, the thickened rigid beam resists flexing, impact and workshop coolant splashes, maintaining consistent parallelism and accuracy even at full extension under daily heavy industrial use.
  2. Standard & Extended Jaw Configurations
    Each model is available with standard jaws or upgraded extended jaws, with maximum jaw depth reaching 400mm for the largest models. Extended jaws allow measurement of deep grooves, internal cavities, thick-walled structures and recessed features that are inaccessible to standard Calipers , greatly expanding application flexibility for complex large workpieces.
  3. Permanent Laser-Etched Dual Scales with Multiple Resolutions
    All scale graduations are precision laser-etched for permanent, wear-resistant readability, with dual metric and imperial unit options. Four resolution configurations are available: 0.02mm and 0.05mm for metric, 0.001" decimal and 1/128" fractional for imperial, to match different accuracy requirements and regional measurement habits.
  4. Open Block & Mono Block Frame Options
    Two frame structures are available to suit different usage preferences:
  • Open block design : lightweight and balanced, reducing operator fatigue during long-hour on-site inspection
  • Mono block design : ultra-rigid integrated structure, delivering maximum stability and dimensional consistency for high-precision large workpiece measurement
  1. 5-in-1 Versatile Measurement Functions
    A single caliper performs five common measurement tasks: outside diameter (OD), inside diameter (ID), step dimension, bore diameter and depth measurement. The precision ground jaws ensure full, parallel contact with workpiece surfaces for trustworthy readings across all measurement modes.
  2. Smooth Operation & Secure Locking
    The sliding carriage operates smoothly with minimal backlash, and the fine adjustment mechanism enables precise jaw positioning for accurate alignment with measuring surfaces. The side locking screw holds the sliding jaw firmly in position for convenient off-part reading and data recording.
