This set of 12 Class M1 calibration weights ranges from 1g to 500g. It contains the following weights: 1 x 1g, 2 x 2g, 1 x 5g, 1 x 10g, 2 x 20g, 1 x 50g, 1 x 100g, 2 x 200g and 1 x 500g. 12 weights in total.
Calibration of balances is one of the most important tasks to perform before use especially if the balance has been in transit. The balances are calibrated prior to shipping and we highly recommend that they are calibrated again when received. The effects of both transportation and changes in temperature can have an impact on the balance accuracy. Please contact Philip Harris Technical Support for advice on how to conduct the calibration.
