For what it’s worth here is an experience that may prove useful to others. It has to do with testing fso2 with an aeration/oxidation kit.
I have struggled for some time with the accuracy of my readings using the aeration method.
My readings always seemed low and the kmeta added rarely brought the ppm up to what I expected according to feedback and documentation.
I have threads here, have spoken to my supplier and to George at FVW.
I acquired fresh solutions and kmeta. Made sure my solutions were at room temperature, used distilled water for cleaning and used a timer for the procedure.
In the end I found the written test instructions called for a slow but steady stream of bubbles when running the test, but going back and watching the video by the supplier, it was anything but what I would call slow and steady. They were aerating the crud out of it!
I retested several batches and with all other things being equal, got a reading approximately 15ppm higher than before. I also recently acquired an SC100A (already owning a PH tester) and received the same readings as the new aeration method and a similar increase over the old aeration test method readings.
Live and learn.
