Calibration Weights: The Foundation of Accurate Measurements / How to Choose Calibration Weights for Accurate Measurement?
They are an essential tool in many industries such as pharmaceuticals, food production, and manufacturing. These weights are used to calibrate scales and balances to ensure accurate measurements. Calibration weights come in various materials, but stainless steel is the most commonly used material due to its durability and resistance to corrosion.
To ensure that calibration weights meet industry standards, they are manufactured according to international standards such as OIML, ASTM and NIST. These standards ensure that the weights are accurate, reliable, and consistent.
Calibration weights are available in various sizes and weight classes, ranging from small weights used in laboratories to large weights used in industrial settings. The weights are typically labeled with their weight, weight class, and the standard they meet.
In addition to standard calibration weights, there are also specialized weights used in specific industries. For example, the pharmaceutical industry requires weights that are traceable to the National Institute of Standards and Technology (NIST) to ensure accuracy and consistency in drug production.
Principal Classes of Calibration Weights:
• Class M1: For standard scales
• Class F1: For precision electronic balances
• Class E2: For highly accurate analytical balances
Calibration weights require proper handling and storage to maintain their accuracy. Regular calibration of calibration weights is also necessary to ensure their accuracy over time.
If you own multiple scales or balances that have similar capacities and readabilities, you may be better off purchasing a set of weights. This way, you know you have enough weights all in one box to calibrate multiple different scales or balances.
