    TDS Probe?

    Is there a way to do this? Amazingly my search for "TDS" turned up nothing, but I can't be the first with this question. I'm looking for a way to get an alert if my RODI is not producing 0 TDS water.

    I.am.suprised there isn't one either as you can get these probes that fit directly on your RO source and product water lines

    The PM2 has four conductivity ranges, the Low range is for this. From the PM2 manual:

    Please do not send me PMs with technical questions or requesting assistance - use the forums for Apex help. PM me ONLY if the matter is of a private or personal nature. Thanks.

    Ahhh thank you Russ! I was looking at a pm2 to put at my mixing station to have a temp probe and salinity in my mixing station, it appears I will need a second one, and will have to figure out how to get the probe inline with my RODI so I am checking the water coming into the tank instead of all that is already in it.

    Doesn't this just measure the ions in a solution?
