Instrument introduction:XPR microanalysis balance is very suitable for accurately weighing the smallest amount of precious samples directly placed in Laboratory utensils of different sizes. Extremely high accuracy and extremely low minimum weighing value enable XPR microanalysis balance to weigh very small samples, thus saving a lot of materials and costs. The measuring range of XPR microanalysis balance can reach 52G, and the minimum weighing value is only 1.4mg (in accordance with USP). SmartGrid weighing tray significantly reduces the influence of airflow on the weighing sensor, thus reducing the stabilization time and obtaining accurate results faster. Professional-level automatic calibration technology (proFACT) automatic built-in weight correction and linear correction to obtain accurate weighing results. The electrostatic detection function can measure the weighing error caused by electrostatic charge and warn the user if the detection result exceeds the threshold set by the user. The electrostatic detection function can not only be applied in standard laboratory conditions, but also can be applied to more challenging environments, such as fume hood.
