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. All tapes are made from a stainless alloy and are precision engraved to ensure accuracy. Tape has diameter range of 2" to 12". Includes certificate of calibration. Tapes are calibrated and include a NIST-traceable certification. Meets ASTM D2166, D2850, D4767, BS 1377:8.
