Hydrogen Peroxide Measurement (H₂O₂)

Measuring cell for hydrogen peroxide with replaceable membrane caps.

The probe head of the H₂O₂ 911 contains two membrane-covered electrodes. When hydrogen peroxide reaches the electrodes, an electrochemical reaction occurs. This reaction produces a current proportional to to the concentration of hydrogen peroxide in the sample. A sufficient flow rate (minimum 15 cm/s) is required for the measurement. We recommend to use a flow cell (available accessory). Interferences: The sample water must be free of surfactants. The sample must not contain chlorine, peracetic acid, ozone or phenol.
