The HI98202 (pNA) is a unique hand-held tester developed for quick and affordable measurement of 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. Most common household water softeners use a zeolite system where 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 from the resin, it has to be regenerated. This is usually determined by estimating the volume of water that goes through the softener and guessing when to change the resin! Since the sodium content of
feed water is not constant,
the resin is often regenerated too early or too
late. This results in extra cost, if the resin is
replaced too early, or risk of damage due
to scaling, if it's replaced too late. With the
pNa, you can measure the sodium content of feed water and exit water in
seconds. When the resin is exhausted, the
HI98202 will read the same value at
each end, and the time is right
for replacing the resin.
