Instruments are generally categorized by the specific physical quantity they measure: How close a measurement is to the actual or "true" value

A "good" measuring instrument is defined by several technical standards that ensure the reliability of its data:

Measuring instruments are specialized devices used to quantify physical properties—such as length, mass, time, and temperature—ensuring accuracy and fairness in both industrial and daily activities. These tools range from simple rulers to high-precision coordinate measuring machines . The ability of the device to maintain its
