I requested Ole Bob test samples from the Robey Mark IV generator a friend uses. I believe this gives me the right to post his testing results.
The addy for this generator boasts 20-80 ppm in 10 minutes, my friend says it does have an automatic shut off. Sample labeled 80 PPM; Conductivity = 18 uS/cc; pH = 6.41; Strong T.E.; Ag = 12.98 PPM; crystal clear. Sample labeled 60 PPM; Conductivity = 15 uS/cc; pH = 6.27; Strong T.E.; Ag = 15.4 PPM; crystal clear. Sample labeled 40 PPM; Conductivity = 10 uS/cc; pH = 5.70; Strong T.E.; Ag = 4.62 PPM; crystal clear. Sample labeled 20 PPM; Conductivity = 160 uS/cc; pH = 7.30; Medium T.E.; Ag = 0.55 PPM; very slight yellow. Sincerely, "Ole Bob"
