Response Time: After equilibration, 2 minutes for 2 mV


The galvanic cell provides an output voltage proportional to the concentration of dissolved oxygen in the solution under measurement without the need of a supply voltage. This value is amplified to obtain a better resolution and measured with the analog-to-digital converter placed on the Smart Water board. This sensor should be calibrated with the calibration solution for more accurate measurements.
