50 Ft Starrett Tape Measure. 530-50 Long Line Tape. Certified calibrated traceable to NIST
The 50 Ft Starrett Tape Measure, also known as the 530-50 Long Line Tape, is a reliable and durable tool designed for accurate measurements. The tape measure features a classic vinyl clad steel case design and a rugged rewind mechanism for single-user convenience. The case also includes nylon rollers at the opening to reduce blade wear, ensuring sustained field use.
The tape measure is produced with high-visibility, easy-to-read graduations and includes a folding hook ring. It comes with certified calibration documentation traceable to Master Standards at the National Institute of Standards and Technology (NIST).
Calibration is performed with transfer standards that are progressively more accurate in the order of 4:1. Starrett attests that the measuring and test equipment and calibrations performed on the tapes are in accordance with ISO 17025:2017, ANSI/NCSL Z540-1, Mil-STD- 45662A. Accuracy-wise, when the tape is supported on a horizontal surface and pulled with tension of 10 pounds at a temperature of 68 degrees Fahrenheit, the overall length will not be in error by more than .100" in 100'.
A note on calibration dates:
Calibration dates are suggested by the manufacturer, but you may select a recalibration date with an interval of your choosing, as long as this is documented in your Quality Manual or other quality documents. Atema recommends a 5-year recalibration date for gauges used as a Master set. Atema certifies that all tools sold are new (never refurbished) and are stored in temperature and humidity-controlled storage.
