Dissolved Oxygen Sensor

Sensor Specifications

Detail

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

Notes

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.
