Clark Electrode Simulator

I'm looking for a electronic circuit that will simulate a Clark O2
electrode. Our student biology labs have many O2 Monitors. In order to
help the instructors quickly troubleshoot problems, I would like to
build them an electrode simulator. This would hopefully give them a
selectable zero and 100% output.

Do you have output calibration values for the various probes you use?
Polarographs?

Thanks Spehro,

The monitors they are using are YSI 5300's. After I posted this I had a
"DOH" moment: Contact Yellow Springs Instruments! One of their tech
staff replied, saying to replace the electrode with six specific high
ohm resistors. Two sets of three, for two extremes of operation. One
for 100%, one for 50% and one for 25%.
