托盘天平又名架盘天平或受皿天平,是中、小学教学实验中常用的计量仪器。它的规格品种较多,教学实验一般使用双盘、单杠杆、等臂式托盘天平,最大称量分别为100g、200g、500g等,感量与最小标尺计量值一致,一般分别是最大称量值的1/1000。托盘天平的灵敏度较低,如果不注重定期检验与维修,称量的正确性就难于保证。
The tray balance, also known as rack balance or receiver balance, is commonly used in teaching experiments in primary and secondary schools. Its variety of specifications, teaching experiments generally use double-disc, single-lever, and other arm-type tray balances, the maximum weighing were 100g, 200g, 500g, etc., the sense of quantity and the minimum scale measurement value is consistent, generally the maximum weight 1/1000 of the value. The sensitivity of the tray balance is low. If you do not pay attention to regular inspection and maintenance, the accuracy of weighing is difficult to guarantee.
