Pl-0977

[johno2412]

Hi will the expansion card pl-0977 read conductivity & redox or just conductivity & ph on a Ghl 3 system

[Gunther]

The card has two switchable inputs:

- Conductivity for fresh or sea warer
- ph or Redox

So it´s possible to read ph and conductivity (fresh or sea water) or redox and conductivity (fresh or sea water)
But it´s not possible to read ph and redox at once nor is ist possible to read conductivity for fresh and sea water at same time

Yes it is the S for sea water so I'm ok with the redox / conductivity option.
Thanks
Paul
