Services, Calibration & Recertification Lab

Pi Tape Texas, LLC's environmentally controlled Calibration & Recertification Lab continues to be the logical source for qualified critique of precision measuring tapes. Our lab is unmatched in its ability to credibly calibrate and certify our tapes and recertify the instruments forwarded for our review.

Pi Tape Texas, LLC continues to successfully complete onsite audits of our internal procedures from outside sources such as GE, Westinghouse and Lockheed Martin. We have also completed a NIAC criteria based field audit performed by Whiting Corporation, Assessment # 12530.





We calibrate and recertify inside and outside diameter tapes, linear rules and circumference tapes. Our company has decades of experience not only in design, but also in the calibration and recertification of a multitude of vernier scales.

We routinely manufacture and calibrate special design tapes, as well as Go/No-Go applications. We utilize precision machines unique to Pi Tape Texas, LLC, installed on anti-vibration tables with high definition magnified optics. We have an assortment of ring gages ranging from 0.375” up to 55.000”. Our optical comparator gives us the ability to check tape accuracy, line by line, to 0.0001”. In addition, we employ our multiple Renishaw XL 80 laser systems for calibration and manufacturing. Pi Tape Texas, LLC is the choice for recertification and calibration for thousands of customers worldwide.

Each Pi Tape® brand precision measuring tape is furnished with a Calibration Report whose measurement results are traceable through NIST to the international system of units (SI).

Statements of conformance are based on measurement results being within the specified tolerances, which are unmodified by the measurement uncertainties. Decision rules as follows:

In Tolerance – Results within specifications;
Out of Tolerance – Results exceeds specifications
