Calibration Weights for Scales & Balances

  SWPI 's world-leading expertise in metrology extends to Calibration Weights or Test weights , weight sets . Our weight portfolio covers weights according to OIML from fifty micrograms to one ton in all accuracy classes. Our test weights are used all over the world, not only for testing balances but also as primary standards in mass laboratories. Calibrating Scale: Premium-quality weights to satisfy stringent testing requirements Calibrating scale testing requirements have become more complex, requiring that the scales survive years of use in rough industrial environments. Ensuring scale calibration is key to extremely accurate and efficient production using a fully calibrated scale. Test weights for scales are important tools for weighing scale calibration. If a scale is not calibrated, it can significantly cost a company financially, and even worse, it can damage its reputation. SWPI ’s calibration Weights are perfectly designed to support testing and calibration

Metrication in Weighing & Measuring System in India

  WEIGHTS play a vital role in the Society. Normally we use it to judge the cost of products while selling or buying. During the ancient period transactions of commodities were being made either through the “Exchange” or “Barter” system which failed to satisfy the need of a common man of the Society. It laid down the foundation of a system of weighment and measurement. But every social structure/Elaka (region) period gave rise to their own system throughout the whole world which could satisfy their local needs to some extent only but failed to cope up with inter-regional/ inter-state or international trade as the world was coming closer very fastly. The French Scientists encouraged by the revolution; assigned themselves to the task of evolving a system using nature as model and natural phenomena as guide to discourage the national/regional susceptibilities, if any. The credit goes to Talleyrand, that in 1790, the French Constituent Assembly took the initiative and entrusted the uphill

The main object of such regulation is to ensure standardized procedures for calibration acceptable to all stakeholders, transparency in the whole procedure, and accountability of the measurement results.      THE LAWS OF LEGAL METROLOGY IN INDIA: Regulation of Weights and Measures were implemented in the early stages of post-independence through the Standards of Weights and

Why Calibration and adjustment are two separate things?

  We calibrate a weighing device to understand how it behaves but we adjust the device to change its behavior. So to change the behavior of something firstly, we need to find how it is behaving by calibration and then we can adjust the same. It is important to find the device’s behavior before making any changes to its behavior. Therefore, it is reasonable and common to calibrate a weighing device without adjusting it. A relationship is developed between a known value (standard) and a measured value with the help of calibration.  Adjusting a balance means that you are intervening in the weighing system, to make sure that the display is set to show the correct nominal value. And Calibration, on the other hand, you are testing whether the display is correct and documenting any deviation.  For all units of measurement, there are some standards established as the basis for a particular unit.  In the context of weighing devices, standards come in the form of Test Weights. The Test Weight is
