This calibration weight set includes one 5KG (~11 lbs) cast iron weight and one 200g chrome test weight. The 5KG weight is finished with black paint. On its side there is a removable brass plug for weight adjustment. This weight set may be used for calibrating scales with 5kg, 10kg, or 20kg capacity. Check your scale's manual before ordering.
Use the 200g weight to test your scale after calibration. Calibration only guarantees correct reading at the calibration point. Testing your scale with a different weight after calibration is important.
These weights have tolerance equivalent to OIML M1.
