Calibration weight sets are used almost exclusively as a standard for the calibration of a range of weighing equipment, they do however sometimes provide a useful comparison guide for improvised weights or devices where the weight is at first unknown. These weight sets are manufactured to extremely tight tolerances and usually take the form of stainless steel or brass cylinders.

There are three main types of calibration weights all of which are classified and approved by technical standards organisations such as NIST, OIML, ASTM and UKAS. The relevant classification of each weight type depends on the resolution of the weighing device (scale, balance etc) and the accuracy needed to correctly calibrate said device. Classifications are as follows:

Class M1 calibration weight sets are used with standard weighing devices like a scale that you would see in a doctor’s surgery or market stall
Class F1 calibration weights are more accurate than M1 and you will usually find them being used to calibrate precision electronic balances in a manufacturing or pharmaceutical environment.
Class E2 calibration weights are used to calibrate highly accurate analytical balances in pharmaceutical environment where the highest level of accuracy is needed, perhaps within production of drugs for human consumption.

Calibration of weights is key across a broad range of sectors as the accuracy of these instruments is relied upon for checking the accuracy of scales and other pieces of weighing equipment. Calibrationhouse therefore offers a comprehensive test weight calibration service at a variety of standards and weighing classes. Most services are offered in our lab, with some onsite capability where needed, please contact us directly to discuss your requirements in greater detail.
