Balanzas de Precisión

A: While precision balances are more accurate and precise than most scales, they feature a lower readability than analytical balances. They often feature a higher capacity and are less sensitive to changes. That means they can be used outside of labs for applications that require a high level of precision but also measure bigger samples in more variable conditions.

A: That depends on your model. For basic compact models, you can go as high as 1 or 2 grams, and as low as 0.01 g. For higher end models designed for lab usage, you should get increments between 0.01 and 0.001g. Always check your readability before choosing a calibration weight.

A: Precision is how close multiple measurements are to each other. If you measure the same sample 5 times, you should get the same result each time. If the measurements are different each time, and they’re not close, you balance is not precise. Accuracy is how close a measurement is when compared to a known value. If you weigh a sample that you know is 0.05g, and you get 0.07, you know your balance is not accurate. Take a read of our blog post "What is accuracy?" for more information.
