HM Digital TDS-EZ Water Quality TDS Tester

This is "exactly" what I wanted. Easy and very accurate. I benched tested it with distilled water then a salt solution that I made up.

Very good product for the price! Good way to check charcoal filter efficiency! (as in knowing when to replace).

Good water tester.

I’m not an expert but I purchase this to check my reverse osmosis set up against a variety of watered bottle which was about 44-50 ppm and my reverse osmosis was 48ppm. Faucet or tap water measured 589ppm which I think is bad. Good luckRead full review
