What are some of the pros and cons of measuring with a micrometer? The micrometer is generally an excellent precision measurement tool. As with most things, the micrometer comes with some advantages as well as some disadvantages. Micrometers are one of the most accurate measurement tools available, measuring as far as the 100 thousandths decimal place on more advanced, digital models. The ratchet creates a uniform amount of pressure resulting in measurements that are both reliable and repeatable. The scales located on the sleeve and thimble of a micrometer function together, ruling out the need for external measurement tools. Also, micrometers exist in highly specialized designs allowing for even more applicability and precision. Finally, micrometers are built to be very durable. You will not break or wear these tools out quickly. As for the disadvantages, micrometers do have a naturally limited range. Bigger objects might require multiple micrometers or larger micrometers, which can get very expensive. Additionally, while the specialization of micrometers is also an advantage, needing a certain type of micrometer for different jobs makes them slightly less efficient. Overall however, micrometers are a requirement for any industrialist and are unmatched in precision.
