  • Specification

Built for precision and versatility, the EG-225F combines a rugged flat-back design with high-resolution measurement capabilities. The flat-back format makes it easier to position in confined or specialized setups. With its selectable measurement modes—Normal, Absolute Zero, and Preset—it adapts to user workflows effortlessly. Adjustable contact force and advanced display modes (like MIN/MAX/TIR readouts) elevate its utility across inspection, quality control, and calibration tasks. It supports multiple output methods to integrate cleanly with data loggers, PC systems, or legacy interfaces.

  • Flat-Back Design – Same performance as the EG-225 but in a streamlined, flat-back format ideal for varied mounting scenarios.

  • Preset, Zero, & ABS Modes – Offers flexible measurement options for calibrations, reference resets, and absolute positioning.

  • Dual Power Options – Includes a built-in rechargeable battery and supports external AC adapter operation for continuous use.

  • High-Resolution Output – Provides precision down to 0.00005″ (or 0.001 mm), ideal for fine measurement tasks.

  • Fast Response Time – Captures rapid dimensional changes with a response speed of up to 20 in/s.

  • Versatile Output Interfaces – Comes with Serial BCD output and supports optional RS-232C, USB, MTI, analog, and relay-based outputs.

  • Adjustable Measuring Force – Set to a standard of 150 grams force (adjustable as low as 25 grams) for delicate applications.

  • Advanced Features Available – Includes directional changeover, reverse display, and TIR (Total Indicated Runout) calculation. Optional wireless data transfer options are also available.
