Scales

XS BALANCE: ACCURATE AND RELIABLE MEASUREMENT

A scale is an instrument used to weigh, or determine the mass, of a sample. It is important to bear in mind that weight and mass are two different physical quantities. The main difference is that mass corresponds to the amount of matter an object is composed of. Weight (or weight force), on the other hand, is the value of the force with which mass is attracted towards the centre of the earth. Since gravity varies in different “corners” of the planet, the difference between weight force and mass becomes relevant in the calibration of scales with a certain degree of accuracy. For this reason, calibration is recommended immediately after installation in a given location.

The main characteristics of a scale are:

- Division: indicates the smallest variation in mass that the instrument can detect.

- Capacity: represents the maximum load that the balance can bear.

- Reproducibility (or accuracy): indicates the agreement of repeated measurements of the same object.

- Linearity: expresses the maximum weighing error that can be observed over the entire measuring range.

The XS Balance range comprises 3 macro families:

- Analytical scales: division 0.0001 g, with a capacity of 220 g.

- Technical scales: division from 0.001 g to 0.1 g, with a capacity from 300 g to 6 kg.

- Industrial scales: division from 1 g to 10 g, with a capacity up to 100 kg.
