Instrumentation refers to the use of instruments and tools to measure, control, and analyze physical quantities in various fields such as engineering, science, and medicine. It involves the design and application of devices that can monitor parameters like temperature, pressure, and flow, ensuring accurate data collection and process control. In the context of scientific research, instrumentation plays a crucial role in experiments and data analysis. Instruments like spectrometers, oscilloscopes, and multimeters help researchers gather precise measurements, enabling them to draw meaningful conclusions and advance knowledge in their respective fields.
