The QM-Height has best-in-class accuracy of +/- (2.4 + 2.1L/600) um.
Air-Suspension Feature: Pressing a button on the grip activates the internal air pump. The base rises on a cushion of air and is able to be moved smoothly over the surface plate. (*note: measurements should not be made while this function is in use as it will cause measurement error).
An easy-to-view, simple control panel enables most measurements to be made with a single keystroke. New features on the QM-Height include a longer operating battery life (up to 1200 hours) and USB and d2 Digimatic output capabilities that displays up to 8 digits total.
QM-Height measures height, height difference (step), inside/outside widths, inside/outside diameters, circle pitch, free-form surface maximum/minimum heights and height difference by scanning measurement*.
Two subdisplay modes display the value from the previous measurements or the value from the zero/origin point. Origin points can also be set from hole centers.
ABSOLUTE encoder maintains the origin: The electromagnetic induction type ABSOLUTE encoder maintains the origin. There is no need to set the origin after turning on the power (except when there is a considerable environmental change).
*Scanning measurement stroke is approx. 1 mm above and below from the start point of measurement.
