The periphery tape, provides a quick, accurate and easy method of reading true diameters of both round and out-of-round forms.

• Perfect for measurement of thin or soft walled parts - large or small.
• Pi Tape gages consist of a narrow metal ribbon bearing special graduations.
  These graduations are designed to convert circumferential distance into diameter measurement so the observer can read the diameter directly from the scale.
• Tapes are checked over master gages at .001'"(.03mm) accuracy for standard tapes up to 144" (3600mm).
  Certificate of accuracy traceable to National Institute of Standards and Technology is furnished.
• Pi Tape gages are a precision tool made of 1095 clock spring steel .
  They require a minimum of maintenance, but we do recommend a quick wipe with an oil moistened cloth after use. A light gun oil works very well.
