Precision Diameter Tape

Diameter tapes provide a fast, reliable method for measuring the diameter of concrete, soil and asphalt cores and cylinders. One reading provides round and out-of-round diameters within an accuracy of .001″ (.03mm) by means of special graduations and vernier scale. Both tapes are made from spring steel and are precision engraved to ensure accuracy. Inch tape has a diameter range of 2″ to 12″ and the metric version has a range of 50 to 300mm. Includes certificate of calibration. Tapes are calibrated and include a NIST-traceable certification.
