Either your TDS meter is knackered, or your Di resin canister is in upside down, or your resin is shot.

How are you measuring the TDS? Is it an inline meter that’s part of your RODI system or is it a hand held meter that you’re just sticking in the tank to take a reading?

If it’s an inline meter then I would absolutely expect that to stay at 0 the whole time. If it’s a handheld meter then it’s possible that there were some contaminates in the tank that are getting mixed in with the water.

Does dust increase electrical conductivity?
Good question. I’m sure he’s fine, I just figured maybe there’s something residual from the build process. My sheets spark at night is it possible fibers pick up on a TDS meter?
