Mitutoyo Series 518 QM-Height Absolute Digital High Precision Height Gauge: 0-350mm / 0-14" (7μm) or 0-600mm / 0-24" (12μm)

SERIES 518 - QM-Height ABSOLUTE Digimatic High Precision Height Gauge

• Slider elevation knob (for travel) and wheel (for measurement) enable coarse and fine height adjustment.
• Inside/outside diameters can be measured via a unique method (detect circle apex by tracing measurement*¹).
• High-performance height gauge with best-in-class accuracy and perpendicularity plus GO/±NG judgement functionality.
• SPC (Digimatic) and RS-232C data output enable incorporation into statistical process control and measurement systems.
• An angled grip is conveniently placed for moving the QM-Height on the surface plate and the pneumatic suspension system enables easy, friction-free positioning.
• Frequent-use measurements such as inside/outside diameter and pitch calculation can be implemented by icon-based commands that also support easy one-key operation.
• Redesigned control panel features a dual-numeric display that shows the difference between the previous measurement value and the current value as well as the current value.
• GO/NO-GO judgement is performed by setting upper and lower tolerances. If a judgement result is out of tolerance the 3-colour LED above the display changes from green to red or orange, so tolerance judgement can be made at a glance.
• Newly developed high accuracy and high resolution ABSOLUTE linear encoder for position detection. Once the origin is set, the origin setting is not required each time you turn the power ON (except in the case of a large environmental temperature change).

• *¹Tracing measurement stroke is approx. 1 mm upwards and downwards from the measurement start point.
