Measuring instrument

A measuring instrument is a device for measuring a physical quantity. In the physical sciences , quality assurance , and engineering , measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Established standard objects and events are used as units , and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained.

NCBI Bookshelf. Working safely with hazardous chemicals requires proper use of laboratory equipment. Maintenance and regular inspection of laboratory equipment are essential parts of this activity. Many of the accidents that occur in the laboratory can be attributed to improper use or maintenance of laboratory equipment. This chapter discusses prudent practices for handling equipment used frequently in laboratories. The most common equipment-related hazards in laboratories come from devices powered by electricity devices for work with compressed gases, and devices for high or low pressures and temperatures.

The History of Measurements

Measurement is an integral part of modern science as well as of engineering, commerce, and daily life. Measurement is often considered a hallmark of the scientific enterprise and a privileged source of knowledge relative to qualitative modes of inquiry. Most but not all contemporary authors agree that measurement is an activity that involves interaction with a concrete system with the aim of representing aspects of that system in abstract terms e. But this characterization also fits various kinds of perceptual and linguistic activities that are not usually considered measurements, and is therefore too broad to count as a definition of measurement. Philosophers have written on a variety of conceptual, metaphysical, semantic and epistemological issues related to measurement. This entry will survey the central philosophical standpoints on the nature of measurement, the notion of measurable quantity and related epistemological issues. It will refrain from elaborating on the many discipline-specific problems associated with measurement and focus on issues that have a general character. Modern philosophical discussions about measurement—spanning from the late nineteenth century to the present day—may be divided into several strands of scholarship.

Materials testing, measurement of the characteristics and behaviour of such various applications—e.g., building or aircraft construction, machinery, or packaging. Mechanical property tests, carried out experimentally, indicate which Constant load-rate test machines employ separate load and measurement units; loads  Missing: quantities ‎| Must include: quantities.

Materials testing , measurement of the characteristics and behaviour of such substances as metals, ceramics , or plastics under various conditions. The data thus obtained can be used in specifying the suitability of materials for various applications— e. A full- or small-scale model of a proposed machine or structure may be tested.
