TG328系列电光分析天平广泛应用于化学分析和实验室的一些精确称量中,其称量结果是否准确,除了依靠砝码和天平计量特性(如臂差、灵敏度)准确外,还取决于天平光标能否自由移动到平衡位置。如果天平光标无法自由移动到平衡位置,则必然造成天平称量结果不准确。在TG328系列电光分析天平使用或检定过程中 TG328 series of electro-optical analytical balances are widely used in chemical analysis and laboratory precision weighing, the weighing results are accurate, in addition to rely on the weight and balance measurement features (such as arm, sensitivity) accurate, but also depends on the balance cursor Can move freely to equilibrium position. If the balance of the cursor can not move freely to the equilibrium position, the balance will inevitably lead to inaccurate weighing results.
