Accuracy of the weighing machine
The foremost purpose of purchasing a weighing scale or any other scale is to note down the accurate weight of the load placed on it. With the recent developments in technology, you get modern scales with more features than one but the main purpose of buying one is always to check the weight.
Digital weighing scales are highly preferred because they are more accurate than analog scales. Unlike analog scales, a digital weighing scale will not have loose springs and so, you will be subject to only precise readings.
