Description

This precision dual-column dial height gauge is a professional high-accuracy dimensional measuring instrument engineered for industrial quality control, precision layout marking and metrology laboratory use. Its rigid twin-column design delivers far superior anti-deflection stability compared with single-column Height Gauges , ensuring consistent measurement repeatability for both height inspection and precision scribing tasks. Combined with a smooth gear drive system and handwheel fine adjustment, it enables controlled, micrometer-level vertical positioning, making it a standard workhorse for mold making, precision assembly and tight-tolerance workpiece inspection.
  1. Rigid Dual-Column Structure with Heavy Cast Base
    Built with two parallel hardened chrome-plated columns mounted on a precision-lapped heavy cast iron base, the sliding carriage travels smoothly along both columns with minimal side play and deflection. This dual-beam construction eliminates the wobble and tilt common in single-column Height Gauges , delivering exceptional measuring repeatability and reliable accuracy even at full measuring height — especially critical for precision layout marking and step height inspection on surface plates.
  2. Gear Drive Mechanism with Handwheel Fine Adjustment
    The carriage is lifted via a precision rack-and-gear drive system, operated by a side-mounted handwheel. This allows smooth, uniform vertical movement for coarse positioning, while the integrated fine-adjustment control enables slow, controlled micrometer-level alignment. Operators can precisely seat the measuring jaw or carbide-tipped scriber against workpiece surfaces and scribe lines, greatly improving measurement and marking accuracy compared with free-sliding designs.
  3. Dual Reading System: Dial Indicator + Digital Counters
    It combines a high-sensitivity lever-type dial indicator with built-in up/down digital counters, delivering instant, error-free readings with no manual vernier calculation required. The 0.01mm / 0.001" high-resolution dial provides fine fractional readings, while the mechanical digital counters display whole-unit values clearly. This dual-readout design enables fast, intuitive reading even under busy workshop conditions, reducing operator eye strain and human error.
  4. Practical Measuring Functions & Optional Upgrade
  • Zero setting at any position: supports relative measurement and differential comparison for efficient batch inspection
  • One-key metric/imperial unit switching: adapts to international drawing standards and global working environments
  • Optional rotary locking device: firmly secures the carriage position for stable reading and repeatable layout work (specify at ordering)
  • Multi-purpose application: performs height measurement, step difference inspection and precision layout marking when fitted with the included carbide-tipped scriber
  1. Multiple Range Configurations for Versatile Use
    Six standard measuring ranges are available from 300mm to 1000mm, covering general workshop height inspection to large mold and heavy component height measurement needs. All models maintain consistent 0.01mm resolution across their full measuring stroke.
