SUPMEA DM2800 용존산소 측정기

SUP-DM2800 Dissolved oxygen meter Measuring principle The oxygen molecules diffused through the membrane are reduced to hydroxide ions (OH-) at the cathode.Silver is oxidized to silver ions (Ag+) at the anode (this forms a silver halogenide layer). A current flows due to the electron donation at the cathode and the electron acceptance at the anode. Under constant conditions, this flow is proportional to the oxygen content of the medium. This current is converted in the transmitter and indicated on the display as an oxygen concentration in mg/l, μg/l, or Vol%, as a saturation index in % SAT or as an oxygen partial pressure in hPa.
