My TDS -1 reads from 0 to 999 not 0 to 2000 and it is calibrated to
measure homemade CS.

The TDS-1 from Hanna Instruments is a good bit cheaper, but it reads
from 0 to 2000 ppm. You'll be using it at the *very* bottom of its
range, which means the accuracy will not be tremendous. Sorta like
measuring grains of sand with a yardstick. Do you see what I mean?
