Measurement Device
A measurement device is a tool or instrument used to measure a physical quantity such as length, weight, temperature, or time. Measurement devices can be simple tools like a ruler or a scale, or more complex instruments like a thermometer, a barometer, or a GPS device. Measurement devices are essential tools that are used to measure various physical quantities, providing important data that can be used to make informed decisions and improve processes.
