Which Contoller Monitors Salinity?

[starrfish]

I'm thinking about buying a controller. I want one that monitors salinity (in addition to ph, temp, etc). I also want one that I can hook up to the web so I can monitor my system while I'm away. Does anyone have any recommendations on one that can do all of the above?

TIA,
Daire

Ah, so when they say they measure conductivity - it's really salinity?

Hi Daire,

Conductivity is not a direct measure of salinity, and conductivity measurements are affected by factors other than salinity. I would suggest you do a search if I recall the subject came up and Greg had some good input (as usual).

Got to get over and see that set up some time I still have your RBTA.
