The QM-Height is used to measure height, height difference (step), inside/outside widths, inside/outside diameters, circle pitch, free-form surface maximum/minimum heights and height difference by scanning measurement.

Mitutoyo America Corp. has added the QM-Height gage to its small tools line. The QM-Height is used to measure height, height difference (step), inside/outside widths, inside/outside diameters, circle pitch, free-form surface maximum/minimum heights and height difference by scanning measurement. It is said to have high accuracy ± (2.4+2.1L/600) microns and a built-in pneumatic flotation system to enable smooth movement over a surface plate.

Two sub-display 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. Highlighted features include:

  • GO/±NG judgment by LED and display symbolsLEDs indicate tolerance judgment status—green for GO, red for +NG, and orange for -NG. Additionally, status is indicated by corresponding symbols appearing on the display.
  • Inside/outside diameters, maximum/minimum heights and displacement measured using a standard probe: Besides height measurement, Mitutoyo’s mechanism and firmware enable scanning measurement of inside/outside diameters, maximum/minimum heights and height differences.
  • Absolute encoder maintains the origin: The origin does not need to be set after turning on the power except when there is a considerable environmental change.
  • New d2 Digimatic and USB outputs: Digimatic and USB ports are standard. Using the U-Wave-T measurement data wireless communication system enables instant transmission of measurement data to a computer via wireless communication reducing manual input errors and improves data reliability and operational efficiency.
  • Increased power supply: 1,200 hours of battery life in continuous use.
  • Air-suspension feature: Pressing a button on the grip activates the internal air pump. The base rises on a cushion of air and can be moved smoothly over the surface plate.
