I bought one of those from you. So far, it agrees pretty well with my
calculations/ estimates based on Faradays Law. I am very happy with
it. Thanks for calibrating it, too, btw. --kathryn

A TDS meter is useful if not all that accurate with its low
resolution readout. Check the calibration in the use range. Even
good ones are sometimes 2 digits off between factory calibrated
identical meters, but can be adjusted to be specific use repeatable. I
adjust each one to agree with a COM-100 @ 10 uS
Since there are no dosing standards that make ANY sense and there's
plenty of room to use intuition, *close* is good enough.

Dear James,
We are in general agreement with your position.
We
have found the TDS-1 to be of immense value to the
average "do-it-yourselfer" .most especially when utilized
for
the lower ppm ranges (5 to 20ppm). While the PWT
unit is superior, we do not deem it worth the
extra
cost
