I was trying to recalibrate my Aquarite SWG so I wanted to get an exact reading. I have reason to believe that it was never calibrated however I thought the cell was not producing chlorine. Here are the results
AquaCheck strip test says 3270ppm (put in 1 inch of water) Tested it twice
K-1766 test says 4400ppm (using Apollo Stirrer) Tested it twice.
Aquarite SWG says 3200ppm
So which test should I believe.
BTW here are the full results
Water is sparkling.
