Redox probe problems

[doggydoc10]

My second redox probe is stuck at 128. Probe is maybe 4 months old. Just started a week ago.

Calibrated three separate times and it goes back down to 128.
Doesn't fluctuate at all during the day

I know it's not right because other redox probe I have is reading at 250-300 daily average

Any ideas?

Antonio,

Have you tried switching the Redox probes and seeing if the problem carries over?

[doggydoc10]

Yes I have.
No changes

Can you please post screenshots of each Redox probe calibration data?

did I understand correctly - swapping the probes sho that both probes are OK but always the same sensor port will not do anything?

this would mean that the port died (for whatever reason) - but: how is it posible then that you were able to calibrate the probe?

what value does ProfiLux show if youput the redox probe into the calibration fluid? is 220mV displayed? or no reaction here, too?

[doggydoc10]

I can calibrate the probe. 220 mv displayed after calibration
But when I put it back in the tank 12 inches away form redox probe 1, it stays around 129-130

i once had this problem, due to electronic interfering..
