Semi-automatic Balance

Semi-automatic balances combine mechanical levers with electronic sensors to automatically complete weighing calculations after manual sample placement. They are used in laboratory settings for routine weighing, formula proportioning, and other weighing scenarios that require partial manual intervention, offering simple operation and moderate cost.
Selection
When selecting, consider the weighing range to cover the weight of daily samples and ensure the reading accuracy meets experimental requirements. Check whether the calibration weights are complete. Pay attention to environmental adaptability, such as resistance to airflow interference, the clarity of the operation interface, as well as stabilization time and repeatability parameters. Confirm durability based on usage frequency, and balance the compatibility between the tray size and sample containers.
