Measurement and Instrumentation refers to the science and technology of measuring physical quantities and the devices (instruments) used to carry out these measurements. Measurement is the process of determining the size, amount, or degree of something. It involves comparing a quantity to a standard unit. Examples include measuring temperature (in degrees), pressure (in pascals), or time (in seconds). The goal of measurement is to quantify a physical property as accurately as possible. Instrumentation refers to the tools, devices, or systems used to measure, record, and control physical variables. Instruments can range from simple devices like rulers and thermometers to complex systems like oscilloscopes or data acquisition systems used in laboratories and industrial settings.
