Even for soft objects like O-rings, it is possible to measure the inner diameter with an accuracy of 0.01mm by closely adhering the tape to the inside of the object being measured.
● Place the work on a flat surface such as a flat table and stand the tape vertically inside it, making sure the tape is in close contact with the inside of the object being measured, allowing for measurement of the inner diameter to an accuracy of 0.01mm. ● Readings can be taken in 0.01mm increments, with an accuracy of ±0.09mm for diameters up to 900mm. ● The tape comes with an English calibration certificate, inspection report, and traceability diagram. ● Even soft items like O-rings can be accurately measured for inner diameter by ensuring the tape is in close contact from the inside.
