Calibration is defined as a process in which an instrument or equipment’s efficiency and accuracy are compared with another instrument or equipment. It is important to note here that, the equipment or instrument you are comparing your instrument or equipment has already met the industry standards.     In more simple terms, calibration can be defined as adjusting the performance of an instrument or equipment according to an already calibrated instrument or equipment. For instance, take the case of a thermometer. To test the accuracy and efficiency of a thermometer, a method is used which measures both the temperature and the performance of thermometer using a real heat source.     Calibration can be used in a variety of industries like the food industry, the manufacturing industry, the heavy machinery industry, medical laboratories etc. Calibration can also be of different types and requirement of different industries. For example, instance, electrical calibration services, which measure the voltage and flow of current in various electrical instruments and machinery, or gas detector calibration services which form an essential part for plants and also for the people working in those plants.
