Stainless Steel Hook Weights - Calibration Weight Set

• Classification of calibration weights

• According to different standards and uses, calibration weights can be divided into different types:

• a. Classification by material: mainly including weights made of iron, stainless steel, aluminum, copper and other materials.

• b. Classification by accuracy: such as E1, E2, F1, F2, etc., where E1 is the highest accuracy level.

• c. Classification by shape: such as disc type, cylindrical type, rod type, etc.

Production and manufacturing of calibration weights

The process of manufacturing calibration weights requires highly precise equipment and strict manufacturing standards. It mainly includes the following steps:

a. Material selection: ensure the purity and stability of the material.

b. Molding process: Use specific molds and processes to shape the material into the required shape.

c. Fine processing: Including grinding, polishing, etc., to ensure that the surface of the weight is smooth and achieves the required accuracy.

d. Quality inspection: Use high-precision measuring equipment, such as electronic balances, to perform quality inspection on the weights.

Maintenance and care of calibration weights

In order to ensure the long-term stability and accuracy of the weights, regular maintenance and care are required:

a. Storage conditions: Store in a moisture-proof and dust-proof place, avoid direct sunlight and high temperature.

b. Cleaning and maintenance: Use special detergents and soft cloth for regular cleaning.

c. Regular calibration: Use standard weights or other equipment to calibrate it every once in a while.
