Description

This H-112 series heavy-duty digital caliper is a professional large-scale dimensional measuring tool engineered for oversized industrial components. It delivers reliable micron-level precision across extended measuring ranges, solving the accuracy and rigidity limitations of standard small-size Calipers when measuring large workpieces. With optional extended jaws and data output capability, it is widely used in heavy machinery manufacturing, metal fabrication, shipbuilding, aerospace and structural engineering for on-site inspection of large parts, welded structures and assembled components.
  1. 8 Large Measuring Range Configurations
    Eight standard models cover measuring capacities from 500mm (20") to 3000mm (120"), matching almost all common large workpiece inspection requirements in heavy industry. The reinforced thickened stainless steel beam eliminates flexing and deformation at full extension, maintaining consistent parallelism and accuracy across the entire measuring range.
  2. Standard & Extra-Long Jaw Options
    Each model is available with standard jaws or upgraded extra-long jaws, with maximum jaw depth up to 400mm. Extended jaws enable measurement of deep recesses, internal grooves, thick-walled structures and hard-to-reach features that cannot be accessed by standard Calipers , greatly expanding application scenarios for large and complex workpieces.
  3. High-Precision Digital Measuring System
    Equipped with an advanced capacitive grating measuring system with 0.01mm / 0.0005" resolution, delivering stable and repeatable readings. The large high-contrast LCD screen displays measurements instantly with no manual calculation required, and supports one-key switching between metric and imperial units to adapt to international engineering standards.
  4. Practical Industrial Functions
  • Any-position zero setting: allows relative measurement and differential comparison at any position, improving batch inspection efficiency
  • SPC data output interface: supports connection to PC and quality control data systems for automatic data recording and statistical process control
  • Manual on/off control: flexible power management for heavy workshop use
  • Fine adjustment mechanism: enables precise jaw positioning for accurate alignment with workpiece measuring surfaces
  1. Industrial-Grade Durable Construction
    Machined from hardened stainless steel with anti-corrosion treatment, the beam and jaws resist wear, impact and workshop coolant splashes. Optional IP54 dust and splash protection is available for harsher production environments. The rugged design ensures long-term reliable performance in daily heavy industrial use.
