measurement of the cost of calibration how to account for1. Measuring instruments can be used to directly or indirectly measure the value of the object to be measured devices, instruments, gauges, and standardized for the value of standardized substances. Measuring instruments are widely used in production, scientific research and people's lives and other aspects of the entire measurement of the legislation is in a very important position. Because the unity of the value of the country, first reflected in the accuracy of measuring instruments, measuring instruments is not only the supervision and management of the main objects, but also the measurement of the technical basis of the department to provide measurement assurance.
