  • Drying process is not needed and any worry about damaged by water is not needed also, because of non-submergence method.
  • Operation cost will be decreased because special jig for each work is not needed to be prepared, and the changeover process for each work is not needed.
  • The management for master work and the conditioning process for test which are needed by differential pressure method is not needed.
  • Less influence of temperature. Wide range of tolerance for WORK shape and WORK deforming.
