ZeroWater ZT-2 Electronic Water Tester Save 50% Off

I purchased this device to check the performance of a water filter I purchased here on Amazon. To my dismay, I learned the water filter was virtually useless. The filtered water was almost the same as the water straight out of the tap. I checked the water from my new Samsung refrigerator and its internal filter was much better than the big under sink filter I purchased. The Samsung refrigerator filter reading was about half of the incoming water reading. Also, I use this to measure bottled water that I buy at Wal-Mart to find the brands with the lowest reading. And I bought a bottle of distilled water and the reading was the same as in air exactly what it should have been. There is no way for me to determine the absolute accuracy of the readings, but it serves my purpose quite well. It is small enough to take with me when I travel to test the local water quality. Of course, some mineral content in water is perfectly fine, but since I cannot determine which minerals are safe is, I just go for the lowest mineral content reading I can find.

When I first received this item it did not work. After writing my first review I was contacted to resolve my problem. I was sent new batteries and the product works fine.

Please ignore my first review.

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''d heard about this water tester from my parents. We have an Everpure ROM system that we''ve suspected wasn''t up to snuff in terms of filtering the water coming out of our drinking water faucet in the kitchen. My parents had gotten a system installed and I guess were pointed at this tester to test the water after the installation.

I got the tester and tried it out against a number of samples. I checked the regular tap water (we''re in Los Angeles so the water quality is okay but not in any way perfect) and it seems our filters are barely better than the tap. 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). Arrowhead was at round 60 and Voss was at 40-ish as I recall.

I guess it''s time to buy some new filters!

The device itself is easy to use (just uncap, press the on/off button, and dip the tip in the water sample). You''ll get an instant reading. Just remove, dry off (or flick-dry) and press the on/off button again.

The only real downside to this tester is that it really just does one thing: tests dissolved solids. So, if all you care about is how well your water filter is working? You''re set here. Otherwise, if you need pH or water temp, you''ll have to look elsewhere.

I had always suspected that our tap water was not that healthy--it tastes hideous. This little gadget pretty much confirmed my suspicions.

For each of the following waters I did three tests. According to the back of the instructions, "000" is the "cleanest water".

Faucet Tap Water = 257, 254, 254

Evian Water = 182, 184, 187

Fiji Water = 91, 90, 93

Nestle PureLife = 51, 50, 50

As you can see the readings were very consistent, even if you bounced around from one water to another.

As far as taste (I tasted all the waters after each measurement), the higher the ppm (parts per million) the "thicker" the water seemed. Which of course makes sense because there are more "things" in it.

But if one wants to argue that the closer the water is to 0ppm, the better it tastes, I''d have to disagree. For example, my favorite water is Evian (with Fiji a close second). So I think another important factor is "What is making up those particles?" in your "Parts Per Million" reading.

So with all that being said, I would advise against using this product solely to determine "quality" of water, but it could tell you if a filter is working or not (which is how I intend to use it once my water filter arrives).
