Sentences with phrase «instrumental measurements»
Instrumental measurements refer to the process of using specialized tools or instruments to collect accurate data or information. These measurements help us understand and analyze various physical quantities, such as temperature, distance, or weight, in a precise and objective manner. Full definition
