So how exactly is a mass of 1 kilogram defined? In 1889 it was defined as a mass of platinum-iridium cylinder, and it's almost equal to the mass of 1 liter of water. Originally there were 40 cylinders made in 1884. To this day it's the only International Systems of Units (SI) unit still defined by an physical artifact. Other units, once represented by artifacts, were quantified in terms of mathematical constants. However, kilogram still affects some of them. Ampere, mole and candela are defined relative to other units, which include mass.
World Quality Day was first introduced in 1990 by United Nations to increase worldwide consciousness of the essential contribution that quality makes toward a nation's and organization's growth and prosperity. The term quality is everywhere, in all aspects of life. For organizations, however, deploying quality advances is a prerequisite for creating a sustainable business.

Dorsey Metrology is one of exibitors at MD&M West trade show. Visit out booth to see complete range of inspection devices that we manufacture. Organized by Canon communications at Anaheim Convention Center, Anaheim, California, United States of America, the MD&M West is 3 days event which is directed towards showcasing various emerging aspects about the latest advances of medical world.
As manufacturers strive for six sigma manufacturing processes, and zero defects, the roll of the quality department has significantly changed. Quality departments must now become actively involved in the manufacturing process from engineering to product packing and shipment.
One of the major traditional faults of an optical inspection instrument is the subjectivity of the operator. It has a very drastic consequence on the measurement. The differences between the operators are commonplace as it is up to the device operator to determine where the feature being inspected begins and ends.
