Pond Boss Forums AERATION Systems questions Fishing temperature and oxygen meter.

MF - Cecil is also correct on this one. Note in the picture the meter indicates the amount of oxygen and temperature at the same time with only one "needle" reading. Meter is indicating or guessing/estimating amount of oxygen based on temp reading. I have one of these "machines" and it is basically just a temp probe. There electronic temperature meters out now that give digital readout. Airguide makes one for $20 that has a 23 ft probe wire and uses AA battery. It is built for use on fish on fishing boats and accuracy is pretty good. Marinas and Cabelas carry them.
