Length calibrator used in the Japanese colonization period (one meter)

A duplicate of a prototype kilogram is a standard kilogram used to ensure a correct measurement of weight. With the properties such as corrosion-resistance, high density, good electrical conductivity (reducing the accumulation of static electricity), low magnetization, and high hardness, it can reduce the inaccuracy of measurement and be preserved for a long time. Its cylindrical shape decreases its surface area, reducing the attachment of dust and dirt. Presently, it is stored in this museum, protected by a glass bell jar from the influence of corrosion, temperature, pressure and humidity.
