Precision diameter measuring tape
Diameter measuring tape: Simply roll it out and read the scale to measure in units of 1/100 mm. Ideal for measuring large outer diameters, inner diameters, and the inner diameter of O-rings.
A measuring tape, known as pipe tape, for accurately measuring the outer diameter of cylindrical workpieces, the outer and inner diameters of pipes, and the inner diameter of O-rings. It is made of a thin tape with special markings (the markings convert the circumference size to diameter), allowing for precise measurement of the diameter simply by wrapping it around the object. The standard pipe tape for measuring outer diameters up to 3,600 mm guarantees an accuracy of ±0.03 mm. All pipe tapes are calibrated before shipment and come with an English calibration certificate and inspection report, as well as an English traceability diagram. In the United States, it is used by many customers, including NASA, the U.S. Army, Navy, and Air Force, General Electric, Boeing, and General Motors.
