O-ring dedicated pipe tape (for inner diameter) RTM7
Even for soft objects like O-rings, it is possible to measure the inner diameter with an accuracy of 0.01mm by tightly 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, ensuring that 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 to an accuracy of 0.01mm, with a precision of ±0.09m 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.
