CCR Posted October 5, 2006 Share Posted October 5, 2006 ok hear is my brick. I set my refractor up with a complete, Spectra Pure 5 stage rebuild, New everything. Set it after about 30 gal run through. Then took to store. against to other refratos, mine was 2 pts. off/ I'm going to get distilled water tomorrow, check, BUT NOT CHANGE the calibration. I want to see where the line is, trying both, will report back Quote Link to comment Share on other sites More sharing options...
drock59 Posted October 5, 2006 Share Posted October 5, 2006 maybe LFS was off? Quote Link to comment Share on other sites More sharing options...
impur Posted October 5, 2006 Share Posted October 5, 2006 maybe LFS was off? My thoughts as well. The water here is actually very good. My tapwater is 23ppm TDS. So we are talking .1 or .2 ppm or even smaller here. I don't think that absolute 0 is necessary in this case. It seems we are talking about absolute perfection here, and its just not needed IMO.

blown65 Posted October 5, 2006 Share Posted October 5, 2006 23tds tapwater is real good. I'm not sure what medford city water is but my well is about 300tds. We have a whole house nano filtration on my dads house/well. Its output is around that. Quote Link to comment Share on other sites More sharing options...

CCR Posted October 7, 2006 Share Posted October 7, 2006 Ok. cleaned and wiped down refracto. tested with ro/di first. let it run 20 minutes first. It read a .0015 higher..... / then recleaned and used Distilled, read at -005. Will leave it where it is. When I originall set it up a few months ago. I used ro/ di then took to store to compair. So the difference is just under .002 different, Not a lot, but enough The same difference they found to. I will stick with Distilled.
