Re: Conductivity Sensor

Hello Luhan,

I'm constructing a Hydroponics system, and need to monitor the conductivity of the nutrient solution.

Any suggestions on what to use for the sensors for stable long-term readings?

I believe corrosion resistance is really important. Titanium is one of the materials used. An example:

Regarding your hydro tree in the picture, what happens when one of the rubber bands snaps?
