Feature(may vary by option.)

●【304 Stainless Steel】: The 304 stainless steel can withstand high temperature, good toughness,is very easy to process,so that the weights made of this stainless steel are durable and have a relatively longer life.
●【Less Spcae】: There is a matching aluminum alloy case packaging, which can make the weights not easy to lose,and the box occupies a small space,can save space,greatly improve the utilization of space.
●【High Precision】: The F1 grade weights can be used for more accurate experimental and sampling quality checks,and the error does not exceed 1ppm, more accurate than M1,with smaller permission error.
●【Flexible Options】: The set has a total of 28 weights and comes with tweezers, providing a variety of options,you dont need to buy another set to complete the needs of different situations,saving effort.
●【Wide Range of Uses】: The weights can be used to calibrate balances,weights,and other equipment,and are a very important measuring tool used to ensure that other measuring equipment scores accuracy and precision.

More precise than M1,with smaller permission error.
Use 304 stainless steel,durable.
The F1 grade weights are without adjust bar.
Note: Each set is different,the error of each weights is with small difference,but the error is within the maximum perssible errors of F1 weights.
