M2 weights

M2 weights are used for coarser class III and class IIII scales and as load weights. MASSLAB calibrates M2 weights in its own laboratory.

Available M2 weights

Our range of M2 weights runs from 1 g to 2.000 kg, made in gietijzer and RVS. For each product the table shows the nominal values, the tolerance according to OIML R111, the delivery time and the price excl. VAT.

Weights with a certificate from our laboratory

Weights in classes F1 to M3 are available with a traceable calibration certificate from our own laboratory. We also carry out periodic recalibration in-house.
