Patent Application No. CN202110258305.2 Method for calibrating hydrogen peroxide concentration sensor

Calibration principle and process

In a closed space, when the hydrogen peroxide solution is in a vapor-liquid equilibrium state, the corresponding first vapor-phase hydrogen peroxide concentration in the vapor space at the current temperature is calculated. A hydrogen peroxide concentration sensor to be calibrated is used to detect the corresponding second vapor-phase hydrogen peroxide concentration in the vapor space at the current temperature. The first vapor-phase hydrogen peroxide concentration and the second vapor-phase hydrogen peroxide concentration are compared to obtain vapor-phase hydrogen peroxide concentration comparison result data. Based on the vapor-phase hydrogen peroxide concentration comparison result data, the hydrogen peroxide concentration sensor to be calibrated is calibrated.
