ORP Probe

For all the ozone users, I need to replace my ORP Probe. What brand probe do you use? Where is the best place to order one? I'm running the Red Sea Aquazone Plus 200 if it matters. I thought these could be calibrated, but I can't find directions on how to do it. I'm getting a reading over over 600 in 400 calibtration fluid. TIA!
 
You can get ORP probes lots of places, just be careful that the connections are the same if you buy a different brand. Some companies (like the one I work for :p ) make probes that have the cable permanently attached to the PROBE, some make them with the cable attached to the MONITOR, and some of them it's a separate purchase altogether. There are also two standard connections, a BNC (like a stereo cable) and a DIN (like a computer cable).

You really don't want to calibrate ORP with solution. Most ORP meters and controllers are factory calibrated, which means you'll have to send it back to the manufacturer to have it calibrated. If you must calibrate it, I would use a mV simulator rather than a solution. Too many things can affect solution to alter the ORP; you'll end up making it further rather than closer to calibration.

Cheers,
Jessica

how would you go about building a mv simulator,sounds like a useful project:)
 
Thanks for the info.:confused: I ordered an american marine probe last night and called it a day.;)
