So I just got my Control Wizard 24/7 ph/tds/temp moniter in the mail from nehydro.com and I can't get the damn thing calibrated.
I started with ph as the thing told me my tap water was 8.9. I adjust down with the 7 solution and the 7 screw to seven then up with the 4's then down with the 7's then up with the 4's, and so on and so on until I can no longer turn the 4 screw any higher and I'm stuck with the thing reading 7 in the seven solution and 3.4 in the four solution. I back the screws off and try again only to end up in the same place fifteen minutes later. Then I try again with fresh solutions and distilled water...same problem.
And Also, when I dunk the tds probe in the 1382ppm solution it read 014 (x10 it says so 140 ppm). I try to adjust the tds up and that screw tops out at 066 (660ppm), a long way from the 138 I'm looking for.
I'm following the one page instructions to the letter including rinsing with distilled water. Is it possible my solutions are bunk or contaminated? Or was there a reason Nehydro was selling this thing for $139 when everyone else wanted $170 or more?
anyway, I'm baffled, if anyone is familiar with these monitors or these problems your input is appreciated.
Oh and after all that, this is the second time I wrote this post. The first time my connection went south right before I pushed send!
