250+ Measuring Devices And Instruments (2023 Updated)

Measuring Device

Last Updated: 4 March 2023

A measuring device or measuring instrument is a device to measure a physical quantity or degree of something in our lives every day.

In the physical sciences, quality assurance, and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. The process of measurement gives a number relating to the item under study and the referenced unit of measurement.

These instruments may range from simple objects such as rulers and stopwatches to electron microscopes and particle accelerators. Read the following list to know more.
