Hey Blast, cool results! I just swapped out all of my fire alarm batteries and they seem to be in good shape (they are backup on an AC driven system). So I have plenty of experimental stock now; but I can't find a no.2 pencil to save my life. Anyway, I really like your idea of making a more permanent setup with the reaction "cup" drillilled for the nodes and fixing them with epoxy! Hacking done right. :-)

Oh, and the multimeter idea would be useful getting some information about the reaction while at home, but I didn't mean to keep it with the kit permanently. Any idea how big the reaction chamber is on the MIOX pen? I'm curious due to the fact that the same chamber/concentration can produce 1-4L of MIOX treatment from the same volume, so time is definitely a factor along with available salt. As I said earlier, I also wonder if they are altering the current. Also, you treated 5ml (total of 6ml) and got 2-4ppm - remember that on non-pure water you'll consume that chlorine... the test is for residual concentration.

Thanks for sharing your results.
