Wondering how to determine that my RO/DI system is producing good water.
In this I bought a PINPOINT Hardness meter.

Straight from the tap, how should the meter read? <-- Yeah to hard to say!

After the RO process?

After the RO/DI process?

Looking for measurements in microSiemens (µS) but both Parts Per Million (ppm) and General Hardness (dH) are good too.

(The conversions are 33 µS=17.9 ppm=1dH...)

And if you have a link to 'somewhere' that spells this stuff out, will appreciate you passing it along... Thanks!
