hello all, granted these are not the most reliable readers nut iv had the following issue. after many headaches and attempts, and mainly thx to AZ iv been able to get my RODI unit working (or at least i think so) correctly. my inline tds reader shows 130 in the IN line and a nice flat triple zero in the OUT line. now i store this water in a 100l canister for future use, today i took out the OUT line of my inline TDS reader and dropped in the canister out of curiosity to see what it would read.....it reads 170. there was some uncleaned water left over (less than half a liter) would this have been enough to foul my water or is the TDS not reading correctly as its measuring "static" water and not water running through its sensors? I will when im blessed with a little more cash invest in a digital TDS reader but for now.....Thoughts?
