Dumb question -- is the Hanna Tester a uS meter? MA

We had samples analyzed about ten years ago and made the correlation at that time and started telling about it. We have been selling the PWT meters ever since for that purpose. TDS meters are not useful otfher than reading about half the PPM and not giving much info about the water purity. They're the equivalent of litmus paper.
