Hi Robert and list. The tds-1 may not measure ppm's but it is still a useful tool. I use it to compare the silver that I make each time and if I get the same reading under the same conditions as when I made the last batch, I can be pretty sure that I am in the ball park with this batch. I sent you a sample to be tested and the test that you ran on the sample showed that the ppm's were about half of what I read on my tds-1. So I take that as a kind of calibration for my tds-1.
