APEX TDS READINGS... HM DIGITAL ALTERNATIVE?

[SAMS]

I am trying to find a solution so that I can read TDS readings through the apex.
Neptune have suggested that I use their conductivity probe and then convert it to TDS.


Has anybody used one of these HM Digital TDS controllers with solenoid valves at all?

Ideally I am looking to do an autoflush on my RO membranes to prevent TDS creep and help to protect the DI resin vessels.

I hope Neptune Systems comes out with either an inline TDS meter or a Fusion-ready camera this year. Either would be awesome!

I found this article, not sure if it’ll help you run some testing...
