Very good question! I actually haven't noticed how these units have run, although I do know that generally having dual TFC membranes is considered "commerical". I did a quick Google, and couldn't find any pictures that were detailed enough to figure out how they are hooked up. I'm very interested to find out as well, as I think I will need to add a second TFC membrane when I move to Saskatoon.

I have never heard this before. AquaFX advertises their digital hand held meter as having accuracy +2% from 0-999 ppm.
