Has anyone had any experience with the HM TDS-3 Meter? I just ordered one from eBay for 18.00.
I don't have an rodi yet. I want to test the distilled water that I use and the local grocery store water machine.
Ahhhh it should be <1ppm. Make sure you rinse and rerinse the container you'll use to do the test with the distilled water in question.
If it's not <1ppm, then it's scam water, or maybe they remineralize the water before they sell it to be drinkable.
I found a cheap used 80$ RODI nasty/dirty unit, but it still produce <1ppm TDS water
