I use this to check my RO system. This works great.

This is a good quality product, solid, easy to use and to read. However, a friend suggested I get it to check the safety of drinking tap water on a trip to several countries abroad. First I tested it at home...it read RED 195 ppm. Boiled water read higher 225 ppm. We have had our water tested and have a softener. Our water has no bacteria, but is somewhat hard. I tested distilled water, it read 2 ppm. I tested the water in Paris, it was 225 ppm. In Beaune, where the water is hard, also RED 227 ppm. So, yes there are dissolved solids in the water, but it is safe to drink. This really did not serve my needs although it works as promised and is good quality. Just consider whether it is useful for what you want to use it for. I have to give it 5 stars because it works exactly as described, I simply followed a friend's advice without reading the fine print because I was in a rush.

For the price, this was a great way to test hoe well my new 5 stage reverse osmosis water filter works compared to my old Brita filter and tap water. Is it accurate? I have no way to know unless I also purchase an expensive water tester. However, it does show the relative difference between the filtered and unfiltered water and the results were really surprising to me. City water was 233ppm, Brita was 179ppm (the filter is about a month old), and the 5 stage filter was 10ppm. So that makes me feel good about installing the water filter in my kitchen. I’ll post photos of the different tests but I did want to talk about the meter. This seems like a fairly common meter, a lot of companies sell it and the price ranges from 10-20 dollars. This one comes in a vinyl case and has a cap to protect the test leads. You just turn it on and put it in an inch of water and you get a reading instantly. The primary reading is parts per million but it also shows us/cm, degrees C, and degrees F if you press the mode button. There is a hold function so you can still read the display after you remove it from the water. Overall quality seems fine, it’s just plastic. There is a color chart on the back of the meter that tells you if your water is witting acceptable range or not. Overall I’m happy with this tester and I hope it lasts so I knew when to change the filters on my 5 stage filter.

Its easy to use, easy to measure the purity of the water abd it the same time scary because lots of water including tap water is not for human consumption. Will recommend to anyone. Get it as a Christmas gift.

I use this for my Zero Water Filter setup and is a quality product for the money it has a hydrophobic surface that makes it easy to get the water off for storing after testing water

Overall, this appears to be a solid TDS reader. It is lightweight, easy to read, and the background colors are incredibly helpful (green for safe, red for nope don't drink it). The reason for my 3/5 star rating has to do with the accuracy. I tested the tester (say that 10 times fast) on water from my sink in a clean cup. After noting the first value, I ran several consecutive trials. The initial value wasn't replicable & often varied in a range between 1 to 20 from the initial value. Over the course of several days I tested it on a number of differing water sources, again with varying results. The values did stay within a certain range, however. Initially I had wanted to return it, but then ultimately realized that despite the lack of consistency in the readings it is good enough for what I am using it for, which is testing water from my ZeroWater filter to determine when to change the filter. This is because the TDS reader included with ZeroWater filters is wildly inaccurate & obviously poorly made. I found that when relying on the ZeroWater TDS reader to know when to change filters, my water starts tasting like fish... But when using this water tester & taking the average of 3 trials, I am able to change the filter before I start tasting that gross fishy taste. Overall, for a consumer's average use that doesn't require extreme accuracy, I would recommend this product. Please note that your mileage may vary & my own tester's variability could be attributed to a variety of things including a manufacturing defect, overheating due to shipping, or user error. Thanks for reading & I hope my review helps you! :)

Really easy to use. Good quality. A great tool to have to test water before and after entering the auditorium.
