Thanks for the feedback
Yes I'll get a photo of resin chamber now. Unit is new so wouldn't think it has deleted yet
Perhaps the cheap TDs meter I just bought is not accurate. I might do a few more tests with it

Assuming this is not an in line TDS meter, then very carefully rinse a small container with that RO/DI several times, then collct and measure the TDS directly in that container. not any larger container sitting around. Dust and contaminants easily raise TDS after the water exits the RO/DI, but you do not care about that rise.
