Notes

EC checked, but calibration not required.
Initial readings for DO at 0.1m, were unexpectedly different from those at 0.5m, considering the water was very turbulent. We repeated the readings at 0.1m in triplicate,and decided to eliminate the initial readings (outliers) and averaged the later three readings.
Raw data is recorded on the reverse side of the data sheet.
