On May 20th, 1875, 17 countries signed the 'Metric Convention', which aims to coordinate and harmonize the measurement systems used in the world today, the International System of Units (SI). The metric system is the measurement system used in the agreement. The basis of the two parameters defined first is the meter used to measure length and the kilogram used to measure quality. According to the 'Metric Convention', an organization was established to manage and maintain such standards around the world, and in France The International Bureau of Weights and Measures (BIPM) was created outside Paris.
We will determine this day of the year, May 20th, as World Metrology Day. On this day, people dedicated to metrology can fully understand and feel that the measurement system that is the basis of international trade and precision measurement will improve the quality of our lives. Important role.
The theme of the International Metrology Day 2018 is the 'quantitative evolution of the International System of Units (SI)'. Although units of measurement such as length and time have been developed to use the universal constants of nature to define more precisely, since 1875 kilograms Has been defined by the cylindrical weight made of platinum and rhodium, that is, the international kilogram original device (IPK) or 'a kilogram standard'.
However, the modern world's requirements for measurement accuracy and stability require a more precise definition of global standards for quality, preferably using standards based on the constants of nature. In 2018, Fortive is finally ready to re The way you define it.
In 2018, Fortive will calculate the final experimental results for the past 20 years and review the proposal. This proposal links the quality unit to the Planck constant, the natural constant used by scientists. In November of this year, it oversaw the The Convention's International Metrology Conference will hear proposals to redefine the kilogram. If everything goes according to plan, Fortive will implement changes to the definition on May 20, 2019.
Fortive Corporation is committed to providing key technologies for people who create, implement and accelerate progress. Measurement is one of the key technologies provided by Fortics subsidiary Fluke. Fortive creates the world's most accurate electrical, temperature, pressure and flow measurement commercial standards Fluke instrument It is a common instrument for the world's top scientists to promote the evolution of measurement systems. Fortive's success is inseparable from the valuable contributions and tireless efforts of every employee of Fluke.
