Mitutoyo รุ่น 500-171-30 เวอร์เนียร์ดิจิตอล Digital Caliper
AOS (Advanced Onsite Sensor) induction type encoder used in top-of-the-line ABS coolant-proof calipers
Thanks to the adoption of the electromagnetic induction type ABS encoder, this caliper can be used without concern for contamination on the scale face during measurement. Detection signal is not affected by dirt (water, oil, etc.) on surface of a scale.
ABS (ABSOLUTE) scale requires no origin setting after power-on and has no limit to response speed.
