How to Choose the most Suitable Scale
Q: Is the capacity the larger the better?
A: Not so. The capacity should be chosen by your need for weighing. For example, if you usually weigh material from 50g-200g, then the 5000g scale is not suitable for you because the sensor of large capacity will take longer time to react when weighing light material. A 300g scale will be more suitable for you.
Q: How to choose the readability?
A:It depends on your demand for precision and the minimum weight of material you will weigh. Please note that scales all has a range of allowable error. If you want the results precise enough to 0.01g, then a 0.001g scale will be more suitable for you. For 0.01g scales, the allowable error range is ±0.03g.
Please make sure that the allowable error range is acceptable for you before purchasing.
Besides, there is still a minimum weight for every scale. The error will be larger if weighing light material lighter than its minimum weight. For instance, if you want to weigh light material like 1g, please choose 0.01g scale; if you want to weigh 1mg, please choose 0.01mg scale.
