MITUTOYO LSM-6902H/6900 High precision laser measuring machine

Producer: MITUTOYO

Category: Optical measuring equipment Tags: LMS Series, LSM-6902H/6900, MITUTOYO

Mitutoyo LSM-6902H is a non-contact laser scanning micrometer, with super high accuracy and precise repeatability. With a wide measuring range of 0.1 to 25mm (equivalent to 0.004-1in), it provides accuracy of +/- 0.5µm and repeatability of +/- 0.03µm. This device supports data communication via RS-232C interface and I/O-Analog, making it suitable for precise and reliable measurement applications in many industries.

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.
