Description

H-150A series heavy-duty vernier caliper is a dedicated large-size dimensional measuring tool developed for heavy industrial measurement scenarios. The thickened reinforced stainless steel beam effectively avoids bending and deformation when fully extended, solving the poor rigidity and unstable accuracy defects of ordinary long Calipers during measuring oversized workpieces. With selectable long jaws and multi-unit dual scales, it adapts to global manufacturing standards and complex deep-structure measurement demands, widely adopted in heavy machinery manufacturing, structural steel engineering, shipbuilding and large mold workshops.
  1. 8 Full-Size Large Measuring Ranges
    Eight complete specifications span 0–500mm to 0–3000mm, covering nearly all oversized part inspection requirements in heavy industry. The whole body is forged from high-grade hardened stainless steel with satin chrome anti-glare surface treatment, featuring excellent impact resistance, coolant corrosion resistance and long-term dimensional stability for intensive daily workshop use.
  2. Standard & Optional Extended Long Jaw Configuration
    Each model is supplied with standard jaws, and upgraded long jaws are optional, with maximum jaw depth reaching 400mm for the largest-size models. Extended jaws can access deep grooves, thick-walled inner cavities and recessed features unreachable by conventional Calipers , greatly expanding application flexibility for large complex workpieces.
  3. Multi-Resolution Dual Metric & Imperial Precision Scales
    Scale graduations are precision permanently etched with anti-glare finish, offering multiple resolution selections: metric 0.02mm / 0.05mm, imperial 0.001" / 1/128". Compatible with international engineering measurement habits, clear graduations resist wear and fading after years of frequent use.
  4. Fine Adjustment Sliding Mechanism for Stable Precision
    Equipped with independent fine-adjustment sliding carriage and locking screws, the sliding body runs smoothly without shaking or backlash. Operators can slowly align the measuring jaws to workpiece surfaces to prevent overtravel, improving measurement repeatability for tight-tolerance large-size inspection.
  5. Fully Mechanical Battery-Free Structure
    No electronic components or batteries required, reliable in dusty, oily, humid and high-vibration harsh workshop environments, with no risk of sudden failure during critical inspection work. Supports outer diameter, inner diameter, step and depth four-in-one measurement.
