This stainless steel slotted mass set includes 10 precisely machined weights arranged on a plastic and metal rack with a carrying handle. The set contains one 10g, two 20g, one 50g, five 100g, and one 500g mass, totaling 1,100g. The stainless steel construction provides excellent corrosion resistance and long-term weight stability. The slotted design allows individual masses to be quickly added or removed during experiments involving force, pressure, torque, or calibration of balances and scales.
