The DO 700 will accept one calibration point in concentration mode. The minimum value is 2 mg/L (ppm), and the calibration window is +/- 40% of the fa

4.2 % Saturation Calibration The DO700 can be easily calibrated in air. For best accuracy, ensure that the barometric pressure value is accurate. Th

8. DISSOLVED OXYGEN THEORY Dissolved Oxygen (DO) refers to the volume of oxygen that is contained in water. There are two main sources of DO in wate

20 Measurement Units One measure of DO in water is parts per million (ppm) which is the number of oxygen molecules (O2) per million total molecules
