Re: TDS Meter
Larry;
1 teaspoon of salt per gallon wiill add almost 2000 ppm to the meter
reading. If you add more than 1/2 teaspoon of salt to the gallon, you will
be off scale on the Hana meter. If you are adding just a little, say 1/8
tsp per gallon, you will add 250 ppm to your reading. To roughly guess the
hardness change figure you will be reading 250(salt)+140(old TDS)=390 ppm
for your 35 ppm hardness. Now the salt is the overriding factor and it woll
be tough to gage hardness with the meter since it is only 10% of your
reading. If the reading goes up by 100, is it salt(evaporation) or
organics, or hardness from dissolved minerals???.
Basically, this means use the meter for your base or makeup water prior to
using any salt and try to keep the reading steady by water cchanges.
