Precision Inside Diameter Tapes
Our precision diameter tapes are manufactured to exacting standards in temperature controlled facilities at 68°F (20°C). The lines and numerals on our standard tapes are engraved and acid etched on a ground surface. The tapes have fixed readings that do not require periodic adjustments.
Our standard Imperial tapes (inches) read to 0.001” diameter with an accuracy of ±0.001” up to 144 inches.
Our standard metric tapes (millimeters) read to 0.01mm diameter with an accuracy of ±0.03mm up to 3,600 millimeters.
Each Pi Tape brand precision measuring tape is delivered with a Calibration Report traceable to the National Institute of Standards and Technology and all calibrations are performed in accordance with ANSI/NCSL Z540-1-1994, ISO/IEC 17025, ISO 10012-1, MIL-STD 45662A and 10CFR, part 21.
