Ken, Sorry, but I can't make heads or tails of Frank's test results--can you translate them into plain english? I'd like to know, not sure if my Ole Bob thermal stir series 2 is the same version you made your test batches with, but I am having the same large (almost half of the PWT reading at auto shut off) drop in uS after a few days storage. I had been kinda surprised a the large drop in conductance. But given my idiosyncratic problems making clear CS, I just had figured it was something unique to here. TIA, paula
