Why don't you simply measure starting and ending current with a milliammeter?
The start current is an indicator of water quality and the end current (or the
difference between the end and start currents) is an indicator of saturation.
If the start temperature is usually the same (room temp, boiling point, or
something you prefer), most of the variables will be accounted for and you won't
need no steenkin' Hanna meters at all.
You can get digital multimeters for $5 if you look.
Hmmm... wrap bell wire around a compass and put a tick mark at the
deflection.... Boy Scientist, 1890...
You don't NEED the Hanna's unless you WANT 'em. Once you've made a working
protocol you prolly will leave 'em in the box.
