Force and mechanical measuring equipment
The Mitutoyo LSM-6902H laser measuring system exhibits the best repeatability in its 25mm/1 in. product class. The Mitutoyo LSM Series LSM-6902H/6900 laser scan micrometer uses an ultra-precise scanning engine to achieve high accuracy, ideal for sensitive or moving parts. The LSM-6902H series is an excellent choice for measuring rollers or measuring tips.

*1: Determined by the value for ±2σ at the measurement of ø25mm workpiece with 1.28sec.
interval (1024-time avarage).
*2: At the center of the measuring region.
*3: An error due to workpiece shift either in the optical axis direction or in the scanning direction.
*4: The area given by “measuring range on the optical axis” x “measuring range in the scanning
direction.”
*5: ΔD=Difference in diameter between the master gage and workpiece in mm.
*6: FDA Class II/IEC Class 2 semiconductor laser for scanning (Maximum power: 1.0mW)
