The XS Analytical Balance permits rapid and accurate analytical weighing by allowing air to freely pass through the slotted grid weigh pan, resulting in rapid stability without adversely affecting the results. The SmartGrid weigh pan is suspended from the back of the weigh chamber, allowing speed and accuracy to come together without compromise. The technology removes buoyancy effects caused by temperature differences that lead to air currents. The air easily flows through the weigh pan without lifting the pan.
