conductivity sensor

[oemtds]

how useful are inline conductivity sensors for reef applications. I designed a conductivity sensor that measures water conductivity and provides all sorts of outputs dc/ac lcd...and i want to know how useful is this.

If it can last for extended periods in salt water without the measurement drifting, then it is extremely useful.

I have them for my Profilux controllers. I feel they are very useful.
