Introduction to Granite

GMT has been in the field of Metrology for the past 30 years


GMT METROLOGY DIVISION has been in the field of Metrology for the past 30 years, concentrating in design, development and manufacturing of all sort of metrological calibration items made of Granite ( Dolerite ). Before studying about GMT METROLOGY product and their features, we need to know what is meant by Metrology . On coming lines give you an idea about GMT METROLOGY and their contribution in this regards.


Lord Kelvin said, I often say that when you can measure what you are speaking about and express it in numbers, you know something about it. But when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind. It is clear from the words of Lord Kelvin that, how vital to engineers is the knowledge of the Science of Measurements (called Metrology).

All engineers, regardless of their branch of specialization, are constantly faced with the problem of measurement. It may be of time, mass, force, temperature, length, angle and so on. Almost invariably, the results of such measurements will determine the course of action the engineer takes there after. All such measurements form part of the science of Metrology.

The mechanical and production engineers are, however, especially concerned with the measurement of length, angle, surface, etc. Before World War-I, Metrology had been applied to engineering to a limited extent only. Since that time, however considerable progress has been made in the application of scientific principles to the dimensional control of engineering products. The accurate control of standards of measurements is essential function in every precision engineering production plant. Knowledge of Metrology and practice in its application is of utmost importance in industry today.
