RDO Sensor Calibration

The optical Rugged Dissolved Oxygen sensor is very stable. The factory calibration should produce readings within 3%
accuracy. If you require readings with greater accuracy we recommend that you perform a 1-point, 100% water-saturated air
calibration as described below.

Calibration 100% Oxygen Saturation

1. Place the calibration cap, with the vent hole, on the top of the calibration cup.

Calibration cap with vent hole

2. Place the sponge wafer in the bottom of the calibration cup and saturate the sponge wafer with approximately 10

mL clean water.

3. Gently dry the probe and sensing material with a paper towel. Ensure that the probe and the sensing surface are

free of water and fouling.

4. Place the instrument into the calibration cup.

5. Wait 5 to 10 minutes for temperature stabilization prior to calibration.
