QM-Height measures height, inside/outside widths, inside/outside diameters, circle pitch (height components), free-form surface maximum/minimum heights and displacement by scanning measurement*. It also remembers the immediately preceding measurement (height component) and displays the difference (pitch) between results below the measurement.

features

series 518 Mitutoyo height gauge A full range of options are provided to enhance operability, including a variety of probe contact points, output to a PC via USB Input Tool Direct and wireless output via a U-Wave transmitter.

  • Best-in-class accuracy ±(2.4+2.1L/600)μm
  • Built-in pneumatic flotation system enables smooth movement along the surface plate.
  • Newly developed high accuracy and high resolution ABSOLUTE linear encoder for position detection.
  • Easy reference icon keys. Possible to measure inside/outside diameter via unique process (detect the circle apex and process by tracing measurement).
  • Various types of optional probes are available.
  • Large size LCD with back light.
  • GO/±NG judgment is performed by setting the upper and lower tolerances. If a judgment result is out of tolerance, the display backlighting changes from green to red, so tolerance judgment can be made at a glance.
  • Slider elevation knob (for travel) / wheel (for measurement).
  • With SPC and USB output.
  1. Remembers an origin point once it has been set
    Does not have to be reset each time the system is turned on.
  2. Go/±NG judgment by LED (red, orange, green) and measurement examples
    LEDs are activated at the time of tolerance judgment – green for Go, red for +NG, and orange for –NG. “-NG”, “GO” and “+NG” also appear on the LCD.
  3. External output
    • Digimatic and USB output are provided as standard.
    • U-Wave wireless output (optional)
  4. Simple button layout and user-friendly icon keys
    • An ergonomic cross key configuration enhances operability for
    setting presets and other settings.
    • Frequently used keys are indicated with icons.
  5. Power supply
    • Four alkaline AA batteries (standard accessories)
    • Also operates on four commercially available NiMH AA rechargeable batteries
    • AC adapter (standard accessory)
  6. Inside/outside diameters, maximum/minimum heights and
    displacement can be measured using a standard probe
    • Besides height measurement, Mitutoyo’s proprietary mechanism and firmware enables scanning measurement of inside/outside diameters, maximum/minimum heights, and displacement.
  7. Pneumatic flotation system
    • Pressing a button on the grip activates the internal pump. The base rises andmoves smoothly along the surface plate.
  8. Probe elevation wheel
    • Allows for fine coarse adjustment during measurement
