Background

At present, the verification of a glass gauge (volumetric flask) is mainly realized by a manual mode, and because the verification process is complicated, the accuracy and precision requirements of a verification result are high, the manual verification speed is low, the efficiency is low, and the verification result is greatly influenced by the personal experience and the operation proficiency of an operator.

In the process of manually verifying the volumetric flask, when the lowest part of the concave liquid surface is about to be leveled with the scale mark of the volumetric flask, the adding amount of distilled water is difficult to accurately control, and the state that the lowest part of the concave liquid surface is just leveled with the scale mark of the volumetric flask is difficult to achieve. When judging whether the lowest part of the concave liquid surface is flush with the scale mark of the volumetric flask, the judgment result has deviation due to personal identification difference of operators and influence of the intensity of ambient light and the like, and the parallel line of the verification result is poor. In order to ensure accurate verification results, the verification times of each volumetric flask are at least twice, the difference of the data of the two verification times is not more than 1/4 of the tolerance of the detected measuring device, and the consumption of manpower and material resources is increased while the verification difficulty is increased.
