I would like to get some recommendations for TDS and pH meters. I was
hoping to find something that is of reasonable cost and low
maintenance. I have tried to research but do not know enough about
the technology at this point to discern what viable choices would be
for me. Any suggestions? Thanks!
Get the lowest resolution tds meter you can. Those that resolve to 1 ppm
are worthless for killy water with any salt, not to mention brackish
Lampeyes, etc. Generally a tds shock of 50% to 200% causes no
osmotic-pressure harm, so really fine resolution is a big waste. Go for
one with a wide measurement range (0-10,000 ppm).
I use the Hanna Instruments pocket meters and have been happy with them,
most of the time. Not waterproof, so don't drop. Waterproof can cost 3X
as much.
