Test Weight Calibration
Test weights are used to check the accuracy of your own weighing equipment such as scales and balances. If you are performing your own calibration checks then it is vitally important that your own calibration weights are within the OIML tolerances.
GNW can certify and adjust where needed OIML M, F and E class weights with fast turnaround times.
UKAS certification of test weights is also available.
