Oops, back to front, variations for ppm to uS sounds better, sorry bout that. If I double the ppm reading on a TDS meter it's close enough to my uS meter. Don't need to halve a conductivity meter. It's about milligrams of silver by weight in 1 litre of water, and short of lab analysis an EC meter gives rough idea of silver content. With my EC and TDS meters I don't see any problem with a TDS meter and doubling the reading, or an EC meter and just reading it as it is. Much of a muchness in the home to me. N.

The variance is large and given the discussions of high ppm recently it got me even more interested.

That's all I do, just halve it, and it's close enough when comparing the 3 meters I use. In the scheme of things with home produced EIS what's a ppm or three anyway?
