Special Window Design Pi Tape

12" - 24" outside diameter only
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 Tapes 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.
