QM-Height Series 518-High Precision ABSOLUTE Digital Height Gage

Series 518
Features
  • 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.

Technical Data

Guiding method: Roller bearing
Drive method: Manual
Length standard: ABSOLUTE electromagnetic induction type linear encoder
Measuring force: 1.5±0.5N
Display: LCD
Power supply: AC adapter (06AEG180JA) 120V battery (LR6x4)

* Maximum values are obtained with the probe at the highest position. Any change of the probe orientation
requires the coordinate system be re-zeroed. With the probe in the highest position, minimum measurable height is 4.53”/115mm.
