While dealing with weights and weighing instruments, you must have come across the term “traceability”. It comes into use frequently, especially in laboratory and manufacturing processes. Though traceability may have a different meaning at different places, here as the leading manufacturers and suppliers of calibration weights for laboratories in India, we are going to elaborate on the meaning and application of traceability in metrology and measurement of mass.
The basic definition given by the Bureau International des Poids et Mesures (BIPM, translated to International Office of Weights and Measures) for metrological traceability may sound a bit too technical. It is the “virtue of a measurement result whereby the result can be referenced through a documented chain of calibrations, each contributing to the measurement uncertainty”.
Let us simplify that definition for you, when we measure the weight of something, we trust that the results will be correct and significantly close to the true value. That trust generates since the weights and weighing equipment is calibrated frequently to ensure accuracy. That’s the chain mentioned in the definition of traceability by BIPM. Calibration weights are like a tree, each weight can be traced back to master weight till the standard reference to the true value.
The standard weight is held in a vault of France and its value has been calculated by refining Planck’s constant. Due to that documented chain phenomena of calibration, if any mistake gets found, it can be easily traced back to its source. Since all the calibrations were documented, traceability provides us with an extra edge to curtail the chances of error in weight measurement.
There are many benefits which are acquired due to the traceability in the metrology. We are putting some major benefits as follows.
For ensuring traceability, the weights and weighing instruments are calibrated by authorized regional laboratories. These laboratories are specifically verified and accredited by reputed organisations like National Metrology Institutes. Meanwhile, these institutes keep themselves checked by international organisations accountable for calibration such as the International System of Units.
All these institutes and the accredited laboratories keep the calibration processes documented strictly according to the defined standards. That phenomenon ensures accuracy in weights and just in case any fault emerges anywhere, gets traced back to the source and rectified along with all the applicable calibrations done through that source.
Whether it is weight or anything else to be measured, accuracy and calibration are important. If you also have weight-related requirements or need to accomplish calibration needs in your laboratory or somewhere else, you can get high-precision calibration weights from Swastik Systems and Services.
We are one of the most experienced manufacturers and suppliers of calibration weights for laboratories in India hence, we know the significance of precision and traceability for weight measurements very well. We offer a huge range of weights and weight-boxes suitable for various applications in diverse industries.
