What is an instrument for measuring the diameter of steel wires on-site?
Thread Content
Looking for an instrument to measure wire diameter with an accuracy of ±0.05um for a diameter of 125um, and one that is easy to use? Could you recommend some? Thanks?
This level of precision requires optical instruments, right?
Are there any recommended optical measuring instruments that are easy to use?

The precision of high-precision micrometers can reach the micron level. Additionally, the poster can tightly wind this wire around a cylinder; after winding it 100 times, they can measure the width of those 100 turns precisely, and then calculate the diameter.
The accuracy achieved using a micrometer still does not meet the requirements; moreover, winding steel wire introduces new errors
