This paper expounds the composition and working principle of the concrete gas content meter,and deduces the theoretical mathematical model between gas content and equilibrium pressure according to Boyle’s law. In order to verify the correctness of the principle,the experimental data were accurately measured,the data fitting equation was obtained,and the fitting curve was drawn. The experimental results show that the mathematical model is in good agreement with the experimental data,which provides an accurate basis for the metrological verification and calibration of the concrete gas content meter. At the same time,in order to improve the accuracy of the measurement,the matters needing attention and the improved method of the experiment are described in detail.
