Frank,
I saw your question on the checking of R.O. water. You want to check both
the ph & dissolved solids. Hanna instruments has a sale going on for both
types of meters. If you go to their web site they have the Hanna TDS-1
dissolved solids meter on special for just $14.90 each.
Try them at:
http://www.hannainst.com/products/promo/usa/usaprmo.htm
BTW they have ph meters on special also for $29.90.
IF/when you order be sure to get the required storage & calibration
chemicals at the same time . It's not a problem with the TDS meter you
just use it straight away but the PH meter requires a special storage
solution to keep from the probe wick drying out.
Hope this helps,
DaveA
