When you are buying a scale from HSCo, we will check the scale in front of you and only if you are satisfied with the scale will we give it to you. However, there is no way to know if your scale is showing the right weight once you leave our store. As per the law you are supposed to keep 10% of the maximum capacity of the weight of your scale. So if you are purchasing a weight scale of 300 kgs, you have to keep 30 kgs alongside with it. A lot of business owners donot keep these weights At Hindustan Scale Company we feel it is always better to keep these weights and count it as a cost of the scale. There are two reasons for that. Firstly you are compliant by law. Secondly, you can always check the weighing scale by keeping these weights on the scale. And weights are not that expensive either.
