This is a discontinued style and only available while quantities last 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.
