    DOscan10 Dissolved Oxygen Calibration The DOscan10 tester allows 1 or 2 points calibration. If you have selected the single point calibration in the setup menu, we recommend that you perform a 100% saturation calibration in the air-saturated water. If the 2 points calibration is selected, the zero oxygen solution needs to be used. During the calibration and measurement, the temperature sensor on electrode must be immersed in solution completely, the solution keeps 0.3 m/s of minimum flow rate to avoid oxygen starvation at the membrane.
