Dual-Reading Precision: Simultaneously measures and directly displays both outer diameter (O.D.) and circumference without manual π calculations.
0.1mm Vernier Resolution: Features a finely laser-etched vernier scale for fast, accurate visual reading on large industrial components.
Accredited Calibration: Optional third-party laboratory calibration and official certification available upon request.
Need a simpler solution for your task? We’re here to help!
