Anybody tell me exactly what these controllers are for one is ozone I think the black one has a probe plugged in to the back the probe is red with a small white led light in the end I will be looking at selling them but must do my homework first they were working on a system I stripped down but before I can sell nead to find out all info then I can put a fair price on them

Orp controller.
The sensor as far as I know needs to stay wet. or in a special container.
Anyway, the Orp controller reads the system Redox potential. If below a set point, it will switch on its outlet. The Ozone unit, plus a small airpump should be on that outlet. Airpump pushes air into the Ozone unit. Ozone outlet goes normally into the skimmer. Although most skimmers do not have a specific ozone nozzle.
Some skimmer bodies, depending on the type of acrylic used cannot be used Ozone.

Yes it did have air pipes on it to a small airpump so what sort of price is this worth advertising it for ?
Depending on the age of the Ozone unit. These small units do not last forever, but then again, I do not know how long can they last. It does depend if you dry the air before entering the Ozone unit.
The Orp controller, if in working order and that sensor is still OK, around R500 to R750 secondhand. They are just over R1000 new. Probe could be "expensive" to replace, about R500. If probe still OK, then R1000 could be OK for controller and probe.
Ozone unit also just over R1000 new. So about R500 secondhand, depending on age.
