Weigh Scales

All you need for weighing. 

A scale is one of the most completely accurate instruments available anywhere. Today, almost all scales are designed to weigh the whole load (no link arms), and most instruments have an accuracy of parts per thousand. Which type of scale you choose to purchase depends on both the type of accuracy you require and on how much you are willing to invest. 

Capacity - A scale's capacity is in brief:   how much load capacity it can withstand. Almost all scales can withstand a 50% overload, without showing anything on their display.
Resolution - This specifies how many divisions the scale has, i.e. the size of each step between each scale interval on the display.
Accuracy - Accuracy is much more difficult to define. In general, in a favorable environment it is not uncommon to have better accuracy than 0.1 promille.
