What Is Measuring Equipment?
Measuring equipment is a generic term for equipment used to quantitatively measure physical quantities of objects.
Instruments that assist in measurement may also be classified as measuring instruments, such as ultracentrifuges that use centrifugal force to separate liquids and oscilloscopes.
Instruments that display measurements may also be classified as measuring instruments, such as energy monitors.
Items used by measuring instruments to make measurements include contact sensors, lasers, scales, light, infrared, and inspection needles. Physical quantities measured include length, object surface roughness, temperature, radiation dose, roundness, and transmittance. Other quantities measured include the percentage of ions present and their concentration.
Measuring instruments vary in size, ranging from hand-held to as large as or larger than a person.
Some instruments are made of metal, which expands and contracts depending on temperature. To prevent expansion and contraction from interfering with measurements, some length measuring instruments must be stored at an acceptable temperature.
Uses of Measuring Instruments
Measuring instruments are used to measure physical quantities of products and objects to be measured, and to use the obtained data for countermeasures and analysis.
In the case of products, it is possible to use the data obtained in the manufacturing stage to take measures against defects. For example, the force a product is subjected to when it is actually used is measured and evaluated to determine if the product will fail or not. The data can be used to improve the product.
Oscilloscopes and other measuring instruments are used to make invisible things such as electric currents visible.
