Weighing scales in supermarkets, balances in gold and silver jewelry stores, truck scales in tollbooths, luggage scales, baby scales, postal scales ... Every day in our daily life we find the balance between scales and scales. Weighing scales and scales are accurate and fair, are inseparable from the weight. Depending on the accuracy of the weighing instrument different needs. The accuracy of the weights have different levels. Different levels of weight in the value transfer process, in addition to the precise measurement of the weight itself, but also by the buoyancy of air and other external factors, China Metrology Institute of Quality Assurance Laboratories are working hard
