Now wait a minute... iodine is an element, #53. Turning water (H2O)
into iodine (I) would be quite the feat. So this part doesn't make
much sense to me.

This also... pure H2O does not conduct electricity. When other
appropriate ionized (acidic/base) elements/molecules are dissolved
with H2O, that solution conducts. And other impurities in the fluid
being tested could also conduct electicity. How accurate can this be
to measure specifically water to PPM?
