AI Technical Summary
Traditional liquid calibration devices are labor-intensive to operate, prone to interruption due to reaction delays, and the components of the calibration liquid separate into layers when left to stand, leading to deviations in the results.
A liquid calibration device with liquid replenishment function was designed, which includes a stirring mechanism, a reciprocating mechanism, a piston mechanism and a controller to realize automated liquid replenishment, stirring and liquid level monitoring, and ensure uniform mixing and quantitative delivery of liquid.
It achieves automation and precision in liquid calibration, avoids the lag of manual monitoring, and ensures the accuracy and consistency of calibration results.
