Not Even a Gust of Wind Will Affect Your Weighing

Even small air currents can stop your balance from settling. But the breakthrough weighing pan – SmartPan™ – on XPR precision balances combats such influences to deliver your results up to twice as fast, and improve repeatability up to two-fold, even in a fume hood.

Our white paper presents empirical test data demonstrating how the effects of air currents can be dramatically reduced.

Weighing is one of the most common activities carried out in the laboratory. An electronic balance does not directly measure a mass, rather the force of its weight. The uncertainty of this force depends not only on the technical specification of the measuring instrument but also on many environmental effects such as temperature variations and air drafts.

This white paper describes the influences of air flow during the weighing process. Recent innovations in the design of the weighing pan for precision balances and scales help to minimise any errors due to air drafts. The results of weighing on the optimised design of weighing pan are compared with those obtained using conventional weighing pans. The innovative new weighing pan makes it possible to deliver results up to twice as fast, even under harsh conditions. As the speed and precision of weighing results (respectively settling time and repeatability) is closely associated with the positioning of the balance, recommendations on factors to consider in choosing the optimum location for the balance are also given.
