Model No. SWPI : 18-20

Test Weights of Model No. SWPI: 18-20 are manufactured as per B.O.T. Recommendation. These Weights are used for calibration of weighing machines. SWPI’s Test Weights are made of high quality pig iron for smooth surface (so that foreign materials may not accumulate on its surface). All walls of our Test Weights are smooth and plane so that number of pieces may be stacked properly. Pure lead is used to adjust the mass value of weight. The adjusting cavity is kept sufficient room to allow future adjustment of mass due to wear and tear.
