I'm getting to like trems method with the PWT
microsiemens times 1.2
It could become the new standard of relative inaccuracy!

Dear list,

Can anybody recommend a good tester for checking Parts per Million (silver)
then a silver tester and
an Ozone tester - to test ozone in the air.

I am at present using Hanna TDS equipment - but not terribly impressed. Any recommendations?

Thanks so much
Gordon
