Your cart is empty.How Pure is Your Water? A TDS meter is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the ZT-2 can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The ZT-2 is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.)

When I bought the Zero Water filter and pitcher last year, I bought the tester that just flashed red if the water was not pure. But I wanted an exact readingr and could not be more pleased with this one, which features a digital readout -- both Zero Water testers. With the digital meter, before I filtered my tap water through the Zero Water filter, the reading showed 207 ppm of dissolved solids. When I tested it with my new meter after being filtered, it read ZERO. I sure save a huge amount of money not buying bottled water!

Seems to work well and reading seem accurate

This TDS tester is easy to use and provides useful readings. Although I cannot verify the accuracy of any particular reading I tend to think it's reliable because I've tested several types of drinking water (tap water, spring water, flavored water with known mineral additives) and the comparative readings make lots of sense. Readings do seem to be affected by changes in water temperature. Auto shut-off protects battery life.

It works great. We live in Las Vegas and the water sucks. My frig filter tests around 500ppm. Reverse osmosis from sears was about 20ppm. These both had new filters and a water company came out and also tested them. He said they are within spec if under 600. I wasn't sure on this until I tested it in distilled water and it came up with a "0". I would highly recommend it.

It works fine but the cap to keep it clean when not in use does not fit tight. Ihave to tape it on

If you have the Zero water pitcher system, you must have one of these. We tested our local water and found the untreated water had mineral numbers over 300. We then tested the water from a PuR and the number went down to 200. With the Zero water, it went to, well, Zero!However, the Zero system tells you to change the filter when the number reaches 6. However, if you're the least bit careless and drip a few drops of tap water in past the filter, the number shoots up quickly. This is the only way we know to ensure we're drinking properly treated water every time.Recommended

I bought this for hydroponics I worked until I boosted my nutrient solution. I had to buy another one with a bigger range. But I guess that my fault.
