Description

This H-101 series dial caliper is an upgraded heavy-duty measuring tool engineered for tough, high-frequency workshop use. Its industry-leading double-way shock-proof damping system protects the precision gear movement from accidental drops and lateral impacts, retaining calibration accuracy far longer than standard dial Calipers . With an optional titanium-coated sliding rail for superior wear resistance, it is built to withstand daily heavy use in machining and fabrication shops where ordinary Calipers would degrade quickly.
  1. Double-Way Shock-Proof Precision Movement
    The internal gear-rack mechanism is fitted with a bidirectional damping buffer system that absorbs both vertical and lateral impacts. This protects the jeweled bearing movement from drops, knocks and workshop vibration, drastically reducing calibration drift and extending service life under heavy daily use. The movement runs smoothly with zero backlash, delivering stable, repeatable readings even after long-term intensive operation.
  2. Optional Titanium-Coated Side Rail (Upgrade Option)
    A titanium nitride (TiN) coating can be applied to the sliding guide rail upon request. This surface treatment dramatically increases surface hardness and wear resistance, reduces sliding friction for smoother jaw movement, and prevents galling and corrosion from workshop coolants and oils. For high-volume inspection stations, this upgrade significantly lowers long-term ownership cost by extending the calibration cycle.
  3. Fully Mechanical, Battery-Free Reliability
    Entirely driven by precision gearing with no electronic components, this caliper operates reliably in dusty, oily, damp and high-vibration workshop conditions with zero downtime from dead batteries or circuit failure. It is a dependable workhorse for on-site measurement and production line inspection where power access is limited.
  4. Complete Range of Sizes & Resolutions
    Six standard configurations cover the most widely used industrial specifications, with measuring ranges of 150mm, 200mm and 300mm, each available in 0.01mm high-resolution or 0.02mm standard-resolution versions. This allows customers to select the optimal balance of precision and cost for their specific application.
  5. 4-in-1 Versatile Measurement
    A single tool performs outside diameter (OD), inside diameter (ID), depth and step dimension measurements. The precision lapped measuring jaws ensure full, parallel contact with workpiece surfaces for trustworthy results across all four measurement modes.
  6. Ergonomic Workshop-Oriented Design
    The knurled thumb roller enables smooth, precise one-handed jaw adjustment, while the locking clamp holds the sliding jaw firmly in position for off-part reading and data recording. The large, high-contrast dial face with a revolution counter allows fast, error-free reading and reduces operator fatigue during long batch inspection shifts.
