Measurement instruments are designed to let you evaluate a range of variables in a product, substance, phenomena, device, person and service. The area of measurement instruments is extensive and services a large spectrum of industrial and commercial applications such as manufacturing, construction, geographic, scientific, medical, technical, agricultural, recreational and household. Measurement instruments can range from a simple every day item such as a plastic ruler more complicated things such as particle accelerators and electron microscopes.
Measuring instruments form a key focus in the function of engineers, scientists, designers and surveyors, etc. There are different types of measurements that require specific measurement instruments. The three basic variables upon which measurements are performed on are length mass and time. Measuring microscopes, coordinate-measuring machines, non-contact probes, calipers, industrial scales and interferometers are some of the types of instruments that are used to measure length, mass and time.
Other types of time measurement instruments include: clocks, calendars, chronometers, atomic clocks, and radiometric dating. Distances and weights are commonly measured by tape measures, odometers, micrometers, GPS, ultrasound distance measure, altimeters weigh scales, balances, and spectrometers. Temperatures are measured with thermometers, thermocouples, and pyrometers. Air pressure can be measured by gauges, barometers, and anemometers. In the electrical field, measurement devices include voltmeters, multimeters, ammeters, watt meters, electric energy meters, electrometers, ohmmeters, galvanometers, and oscilloscopes.
Other objects that are commonly measured are: light, sound, speed, flow, pH level, chlorine level, and hardness. Humidity is measured with hygrometers and some other common measurement instruments include Geiger counters, spectrometers, and colorimeters.
If you want a measurement job done properly you must make sure that you are using the proper measurement device and that it is giving you accurate readings. These instruments are depended upon to be reliable and accurate. The degree of reliability and accuracy of a measurement instrument is usually indicated in the instrument’s specifications. Most experienced workers will be able to tell if the instrument is working properly or not and will generally be able to adjust it to get it to work to its specifications. A lot of measurement instruments are regulated by national and international standards to make sure that the instruments have been manufactured properly and are working with accuracy.
