TDS Readings...
I finally got a TDS meter to check the water coming out of my RO/DI.
The meter came pre-calibrated, so I haven't recalibrated it yet....and I got readings of 17 on my tap water, and zero on my RO/DI water.
Is this absurd? Or do we have really clean water here is Coquitlam? Or is the TDS meter clearly not calibrated?
