Working Principle

1. The working principle of analytical balance is based on electromagnetic force balance and high precision sensor technology. When the sample is placed on the weighing pan of the balance, the electromagnetic sensor measures the mass of the sample and balances it with the reference mass through the feedback system.
2. Electromagnetic Sensor Feedback: The electromagnetic sensor ensures that small changes in the weighing process can be responded to quickly by applying an electromagnetic force that matches the sample mass.
3. automatic calibration mechanism: the balance built-in temperature change sensor, regular temperature fluctuations in accordance with the automatic calibration, to ensure stability after a long period of use.
4. micro-sampling support: digital signal processing technology enables the balance to efficiently identify small mass changes, suitable for powder, liquid and other samples of micro-sampling operations.
5. Multi-mode operation: Through the built-in processor, the balance can automatically switch to different weighing modes, such as percentage weighing, counting weighing, etc., according to the user’s needs.
