BRAND NEW HI 98202 Economical Pocket Tester to Measure Water Hardness
DESCRIPTION
The pNa is an easy-to-use and inexpensive instrument for determining
water hardness/softness. The hardness of water is due to the presence
of magnesium and calcium. These make washing difficult, waste soap and
create unpleasant scum and scale deposits. With a zeolite system, the
calcium and magnesium ions are substituted on a one-to-one basis with
sodium ions from a conditioning resin. Once all the sodium ions are
exhausted, the resin has to be regenerated. This is currently
determined by estimating the volume of water that goes through the
softener and guessing when to change the resin!
Even though this
may work in some cases, it fails in most since the sodium content of
feed water is never constant. As a result, either the resin is
regenerated too early, and waste resources, or too late, risking damage
due to scaling. With the pNa, you can measure the sodium content of
feed water and exit water in seconds. When the resin is exhausted of
sodium, there will be no exchange and the pNa will read the same value
at the two ends. Only then should the resin be changed. pNa takes guess
work out of resin regeneration!
