F1 class weights

F1 Class Weights

These weights are of high metrological accuracy and are used as reference standards for calibrating other lower class weights like F2 and below classes, F1 class weights are integral(1mg to 200 g) /two-piece (20 g to 50 kg) type weights, These weights have adjustment cavities for adjusting the weights(20 g to 50 kg). These weights are appropriate for the calibration of medium-precision analytical balances
