Does anyone have any news or experience with the HI772? It supposedly is a more accurate test than the HI755, reads measurements in dkH, and also uses a powder for the reagent. I don't really mind using my current ppm and just multiplying by 0.052 to get dkH but with liquid reagent recalls going on and the switch to a powder it's got me worried the HI755 may not be as accurate as I thought.
