STEEL MATERIAL: Weight test scale set steel construction of calibration weight for well stability corrosion resistance, calibration weight good quality and durable scale equilibrium calibration tool can be used for a long time without affecting the accuracy of measurement
EASY TO USE: This scale weights set is the obvious choice for keeping your precision scale calibrated and accurate,the tweezers make it convenient to pick the weights, and anti-static design makes more accurate measurement
HIGH ACCURACY: Calibration weight permissible error is -0.003 to +0.003g, suitable for laboratory, commercial experimental and daily life use, weight test scale set also can be used for digital scale jewelry scale
17PCS PROFESSIONAL WEIGHT SET: This precision calibration weight set includes 17 gram total 500 gram, and scale equilibrium calibration tool can meet a variety of weight measurements, and the accuracy is relatively high
NOTICE: Be careful not to touch the hand directly when using calibration weight will cause measurement deviation, the steel scale weight cleaning cloth and brush are good for reducing error and keeping clean
