All Pi Tapes® are issued with an individual calibration certificate which is traceable to the US National Institute of Standards and Technology.
They are now manufactured with state of the art processes and calibrations to ensure your product delivers highest level of accuracy on a consistent basis.
Pi Tape® instruments have been relied upon for many years on some of the the most advanced US Aerospace projects by NASA and Lockheed and Boeing.
These small and easy use tapes will ensure your rollers are measured to perfection quickly.
1) 1095 spring steel is unquestionably the finest steel available for precision diameter tapes where thermal expansion and minimum stretch under normal operating tension ranges are a primary consideration. Pi Tape® has received spring steel tapes for recalibration service which were manufactured over 50 years ago and are still within our tolerance of 0.001”. A light film coating of LPS3 oil is the only maintenance needed for these incredibly accurate instruments.
2) Our 716 Stainless Steel, a specialty steel manufactured by Uddeholm, is utilized in more corrosive environments. Although stainless steel is a softer material with similar thermal expansion qualities as spring steel, it is used effectively in a multitude of industrial applications.
3) Our blue easy to read utilizes 1095 spring steel and is an extremely durable instrument, often utilized in low light environments or highly reflective conditions.
4) The white easy to read is manufactured using 1095 spring steel or, on special request, 716 stainless steel. These tapes are very popular and can also be used in low light applications. This instrument relies on a coating for the surface of the tape and should not be exposed to paints, solvents or corrosive work environments.
