In modern metrology, weights are standard measuring instruments for transmitting weight values.The mass value is based on the original platinum-iridium alloy kilogram stored in the French International Bureau of Weights and Measures as the only reference device.Countries all divide weights into national kilogram standards, national kilogram sub-standards, kilogram working standards, as well as working standard groups composed of multiples and weights of kilograms and various working standard weights.

Why Calibrate Weights Regularly
We all know some knowledge about using weights. Although weights are rarely used in our lives, they are still needed in many experiments and debugging products around us.When we use weights, we need to calibrate them regularly. Why do we do this? Today I will tell you why we need to calibrate the weights regularly.
Weight is a calibration standard. In our actual measurement process, we will find that many electronic scales and electronic balances use weights. The weight of the weight is constant, so sometimes the weight is a symbol of fairness, which determines whether the electronic balance and electronic scale meet the standards we set. This standard symbolizes fairness. Sometimes weights made of different materials may be stored in improper places, corroded by certain irritating substances, as well as due to air and temperature. A series of errors are generated, so the weights need to be calibrated regularly to ensure the accuracy of the nominal value of the weights. Weights are the embodiment of a mass unit and have a certain mass. They are used to measure the mass of objects and to stabilize various balances and scales, so they need to be calibrated regularly.
It can be said that weights are not only the weighing devices used in our experiments, but also the scale in each of our hearts. It represents the standard for the entire industry, especially for large mass weights. Many electronic scales will be debugged according to our standards for large mass weights when they first adjust the system. This is why we have to develop the habit of calibrating weights frequently. . Therefore, when you usually use these weighing devices, you must develop the habit of calibrating these products frequently.
