This calibration weight set includes one 25KG cast iron weight and two chrome test weights (200g and 500g). The 25KG 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 25kg and higher capacity. Check your scale's manual before ordering.
Use the 200g and 500g weights 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.
