Weighing scale capacity versus resolution
When you are looking for a scale to meet your needs you should have two facts clear in your mind based on your needs. The two facts are what capacity scale do you need and what should be the resolution of the scale. The capacity is the heaviest weight that can be measured by the scale without causing damage to its internal components. The resolution is the smallest increment that will show up as a difference on the scale reading, the resolution is thus how accurate the scale is.
A scale will typically not be able to weigh very heavy objects if it is able to give a very high resolution of say a few micrograms. So even a very highly sensitive floor scale will not be as sensitive as an analytical scale which cannot weigh heavy objects but can weigh very small weights very accurately. Similarly a scale that is able to weigh very heavy objects will not be able to deliver a very high resolution. So you will not have the comfort of an option of a scale with a very high capacity and very high accuracy. But since all industries have scales developed with them in mind you will be able to find scales with fairly high capacity and fairly high accuracy as well. These scales though will be relatively expensive. Of course you should not spend more than you need to and if you do not need either very high capacity or very high accuracy then you should opt for a scale that meets your needs and does not cost as much. For most types of scales such as quality floor scale you will be able to find scales with varying capacities and resolution. You will get the most value for your money if you will pick the right one.
