2025 New TDS Meter Digital Water Tester, Professional 3-in-1 TDS, Temperature and EC Meter with Carrying Case, 0-9999ppm, Ideal ppm Meter for Drinking Water, Aquariums and More

I use this for everything. It does great reads. It’s very accurate as I’ve compared it with others. I would buy this again.

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.

Works well, good price.

Quick tester for water quality. I originally purchased it to see if the water in our newly purchased home was good enough to drink. Turns out it was all hard water. Even after installing reverse osmosis filter I still use it. It gives you a reading within few seconds.

Seems surprising accurate. I have very hard well water and sure enough it gave me a reading of 567. About what I expected. I then tried it on a bottle of store bought water. It read 27. I then tried distilled water and got a reading of 0. Those reading are what they should be.

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

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! :)

It’s very convenient to test your water at home any time.
