Mark, if I'm not mistaken the Hanna checkers have a margin of error of +/- .04 ppm.. your not that far off from Triton, I think.
I used to own 3 ulr Hanna checkers. When I used them, one always gave me a reading around .1 another always said 0 and the third said something in between but closer to the higher level.
I gave up using them for this reason.
I guess between the three, I was probably getting an accurate reading by taking an average but it was a tiresome process.
