* The MTY-7000 equipped with specially designed linear gauge measuring heads measures the pet bottle & preform bottle of PCO


  1. Measuring time is as short as 4 seconds in any one direction
  2. The MTY-7000 offers an accuracy of 4μm or less in terms of σ when repeated measuring the master gauge 10 times at a fixed point
  3. The measured values are digital displayed.
  4. GO / NG judgement result is indicated by the lamps. (Tolerances can be set as desired)
    GO:The green lamp lights
    +NG: The red lamp lights
    -NG: The amber lamp lights
  5. The measurement data can be output via the RS-232C interface.
  6. The MTY-7000 is a semi-automatic measuring system that allows easy operation and simplified measurement.
  7. With a small CCD camerea, thecondition of workpiece (pet bottle preform) setting can be checked.(12-inch monitor is supplied together)
  8. The MTY-7000 is designed with operational safety in mind.
  9. The workpiece (pet bottle & prefoem) can be measured from two directions (from the angles at 0°and 90°). (Automatic 90°-workpiece-rotation function is optional)
