Sensor specifications Sensor type: Galvanic cell Range: 0~20mg/L Accuracy: ±2% Maximum operation temperature: 50ºC Saturation output: 33mV ±9mV Pressure: 0~100psig (7.5Bar) Calibration: Single point in air Response Time: After equilibration, 2 minutes for 2mV

  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.
