Page 5: Introduction
The 5905 probe is designed for use with all YSI dissolved oxygen meters, except for the Model 55 or Model 95. It must be used with an adapter (5011) in order to be used on the Model 5000 and 5100. -
Page 6: Operating Principals
PERATING RINCIPALS The 5905/5010 BOD probe is a voltammetric (polarographic) sensor of dissolved oxygen. An oxygen permeable membrane covers an electrolytic cell consisting of a cathode and an anode. This membrane acts as a diffusion barrier and an isolation barrier preventing the fouling of the cathode surface by impurities in the environment. -
Page 7: Using
Note: The 5905 must be plugged into a YSI meter and the stirrer power plug must be plugged into its power adapter. The 5010 must be plugged into a YSI meter only, as it gets its stirring power from the 5000/5100 instrument. -

Page 9: Warm Up
Every time the meter is turned on, the 5905/5010 BOD Probe must be allowed to warm up for about 30 minutes before taking the first reading. This allows the probe to use up all the oxygen retained in the cap. New Probe Break In (Motor Off) For best results, please allow the probe more than the usual 30 minutes to warm-up after the first membrane is installed. - Page 10 matte finish.

After prolonged use it may become necessary to clean the anode.

Page 11: Rocedures And Precautions
PERATING ROCEDURES AND RECAUTIONS IMPORTANT Intended Use The 5905/5010 probe is intended for laboratory use, not field use. It is not waterproof and should never be immersed past the taper on the stem of the probe. Air Calibration When calibrating in air, make sure there are no water droplets on the membrane. - Page 12 average replacement interval is one to two weeks. Probes in constant or heavy use may require more frequent membrane changes. Interferences Hydrogen sulfide, sulfur dioxide, halogens, carbon monoxide, chlorine, nitric oxide, and nitrous oxide can cause the probe to give erroneous readings. If you suspect erroneous readings, it may be necessary to determine if these are the cause.
