jeffreythree - Oxygen sensor? So you can see if that 9.5lbs bass will live to see 10?
You have most of the answer, so I am going to let the rest of Furhead Wheelchock out of the bag, er ICM.
YSI's EcoSense DO200(Dissolved oxygen/temperature meter) requires calibration close to the temperature of the sample for maximum accuracy.
The probe goes into the evacuation stack. The stack is filled with ice and capped. After about an hour the probe stabilizes at 35 F degrees.
You may be wondering why such a low calibration temperature? We will be monitoring the D.O. and temperature under the ice of Bremer Pond during the ice cover period of winter. The water temperature should be in the 32 to 42 degree range for most of the winter (we think).
You may also ask, �why not just put the probe in a bowl of ice to calibrate it?� There are a some �real� reasons, with the over riding factor being; how much fun would that be?
