Question: Is this the sme TDS meter included with some of their products!
Document: I needed it to test the water in the city. It works well. I purchased a Zero Water system. It didn't come with a good meter.
The second round of testing results were vastly different. As much as 30%-50% different from the readings a few hours earlier. I did a third test awhile later with varying results again.Since I can't judge which, if any, of the reading are the most accurate, I'm returning the meter.
Fun. Tap was at around 180 on the meter (ppm). The "filtered" faucet was 160. At least it was doing something.I did some additional checks against bottled water testing against Arrowhead (bulk mineral), Dasani (purified) and a bottle of Voss (not-so-bulk mineral) my wife picked up at a restaurant. As you'd expect, Dasani was at zero (it's just purified tap essentially).
And yes, there are areas that bad in this country. But not many.This Meter is meant to understand whats going on behind the scenes of your water. It does not mean a low reading is safe. It just means there are less dissolved solids which is necessary tool in reef keeping, food/drink creation, among other things. It WILL NOT meter safety concerning E.Coli and other bacteria.
I tried this out on my tap water, then I tried it on my filtered water, and lastly I tried it on some bottled purified water. I got similar results for each test that I did. I don't know exactly what this thing is teesting for, but I think that it is total dissolved solids (TDS). You just don't need water to be that pure.
For those complaining about their Brita's and home water filters. Sediment and chlorine filters do NOT remove TDS at ALL. They do improve water quality by removing sediment and chlorine though.Can you turn on a button and dip in water? Then you too can know how good (or poor) your water quality is. This unit comes with batteries.This is also made by HM for Zerowater, it is a rebranded basic unit.
I purchased this TDS water tester based upon other reviewers' comments, especially the low rate of defective units and the reliability of readings. I haven't owned the unit very long, so I'm in no position to comment on the durability of the unit, but it seems well-built. Equally important is the fact that repeated tests on the same water produce consistent readings. The readings I obtained never varied for the same sample of water.
One of the reviewers is confused. This tester tells you nothing about safety or purity of the water. It measures TDS (Total Dissolved solids), the amount of minerals etc that are dissolved in the water. It tells you nothing about purity. I use one for testing the efficacy of my reverse osmosis filtration system. When the water coming out of the RO filter does not have at least 95% fewer TDS than the water going in it is time to change the RO filter membrane.
I had two of these devices, and,unfortunately they were totally INCAPABLE of testing my water purity in a timely manner. There is a significant delay between the time I need to change my filter and when it actually measures the harmful TDS. Said another way, my taste buds confirm that it's time to change the filter, but the ineffective tester still indicates "000". Since I can't rely on the tester to do an efficient job, I depend on my taste buds to do the testing.
used it on tap water and compared it to Ro water showed 85% reduction in hardness. Satisfied with the purchase
Answer: Yes, it was the same meter that was with the original ZERO WATER!  It works fine.
