276	2011-01-24	Lab none	Calibration	Lab none	On January 24, 2011, Jaclyn Hatala calibrated 2 CS511 Sensorex dissolved oxygen sensors in the lab. 1. I filled the caps with water, to make sure that the membrane was secure and not leaking. 2. I emptied the caps and filled them with the electrolyte solution provided. 3. I attached the two sensors to a datalogger with a multiplier of 1.0, and recorded data every 10 seconds for 15 minutes with the sensors out of water 4. I calculated the multiplier by the equation: M=P/R provided in the manual, where P is the given atmospheric O2 concentration given the room temperature and pressure (in this case for 24C and sea level, 8.09ppm) 5. The sensor was labeled DO_3: coef 02352ppm/mV calculations are in DOcal_24Jan2011.xlsx.
