Hey guys, I upgraded my rodi system last week. I've been making a ton of water. I went to do a water change on my tank, and was going to test the SG of the water using my Milwaukee digital refractometer. I take some fresh rodi I've been using for top off, to calibrate the refractometer. I keep getting this "LO" error. I looked the error up, and it says wrong calibration used to zero instrument. Use distilled or rodi water. Hmmm.
Now to the rodi system. It started as a 90gpd, 4 stage system. I then added a brs dual di. I have since updated it to as follows:
1st stage:rosave.z 1 micron sediment filter
2nd stage:matrix 5 micron carbon filter
3rd stage: matrix .6 micron carbon filter
4th stage: spectrapure RO membrane
5th stage: spectrapure di silica buster
6th stage: brs color changing di
Tds into the membrane is 185.
Tds out of the membrane is 2.
Tds out of the di is 0.
Any idea why my refractometer won't calibrate, or why my water wouldn't be rodi? All help is appreciated.
