    Can I Test freshwater alkalinity with Hanna Marine Alkalinity Checker® HC - HI755?

    The Hanna Marine Alkalinity Checker HC - HI755 is intended to be used for saltwater, but since it uses the same lens as the HC - HI775 so I was thinking that maybe is possible to use the HC - HI755, but I would like to hear your opinions.
