2024 All-New 4 in 1 Tds Meter Digital Water Tester - Accurate and Reliable TDS EC & Temp(°C,°F) Meter - 0-9990ppm - Professional Testing for Drinking Water, RO/DI System, Aquariums etc

I bought this for my home, office, and even camping trips, and it’s exceeded all expectations. The 4-in-1 functionality (TDS, EC, °C/°F) is incredibly useful, and the readings are consistent and precise. I tested my bottled water, tap water, and even my hydroponic nutrient solution, and the results were spot-on every time.The hold function lets me take readings without rushing, and the auto-lock prevents accidental resets. The sleek, durable design feels premium, and the lifetime support gives me confidence in my purchase. I’ve already gifted two to friends—it’s that good! A+ for accuracy, usability, and value.

It works as it's supposed to only for detecting "good" pure water such as distilled and purified water. I used it for distilled water with added minerals to make it into alkaline water and it went up to 147 (considered as high hardness water). I bought a bottle of Smart Water alkaline water and it went up to 136. So, minerals in water is considered impure by this tester, but alkaline water can be good for you too. So, expect it to give a higher reading on alkaline and electrolyte water.

2024 All-New 4 in 1 Tds Meter DigitalGreat value, appears to be reliable enough (ball park range) TDS Meter. While it has some nice bonus features as in temperature and electrical conductivity measurements, we were primarily looking for the TDS measurements; the backlit LCD display with numbers and color makes for easy readings within a few seconds or so.Managed to test several types of drinking water from sink water to different bottle waters as well as different filtered water from different RO systems, at home and outdoor water vending machines. Since some portable home RO systems have a built in TDS system we were able to effectively somewhat compare and back test the results. Short of assuming and relying on any one single measurement by itself we took a combined approach to get a sense of their accuracies; what we found was that the TDS results were generally a little off of each other by 10-40ppm, but still in the “ball park range” so that it would make sense to use it as a gauge, rather than assume perfect accuracy.

I first discovered one of these because my “total water system” man had it and used it to test the water and I said what is that?I ordered it from Amazon and now I’m hooked on it.Tested the water because it’s well water and oh my God I could not believe it. The levels were so high and you don’t even know it until you test it.I recently moved to an apartment complex, and the numbers are higher than what they should be.Easy to read brightness. Functional. Quality product.

Very good product. My water quality is score 18, that it is IDEAL if between 0-50. I installed the three stage reverse osmosis water filtration system in may 2023. I change basement cholorine filter and first floor filters in jun 2024. Now, it is just me in the house, so not compare to 4 people usage. I will do it next june.Thank you for saving me money. Very easy to use, recommend to anyone!!!!

This product works! The only thing I'm disappointed about is the poor quality of my own water. This tester displays that my Tap Water has 334 ppm TDS, which means "Scale Will Form." What's coming out of my Refrigerator Filter is 230+ ppm TDS, which means it's only "Marginally Acceptable." That's not good enough for me, so I must complain to the filter company! My bottled waters show 19 ppm TDS, which is great, but could be better!

I’ve never used a water tester before, but this one was super easy to use. Just turn it on, stick it in the water, and boom—instant results. The screen is big and clear, and it tells you the TDS, temp, and other stuff.I tested tap water and bottled water just to try it out, and the numbers were decently different. I even tested it on my reverse osmosis purified water to make sure it was filtering correctly and itnworked great. There’s even a chart on the back to help you understand what the numbers mean.Overall, it’s actually pretty cool and simple to use. If you’re curious about what’s in your water, this thing gets the job done.

I decided to get this because i was told even our bottled drinking water was having contamination issues, so i tested my faucte water and it was 233 and the brita filtered water was 148 which is high for something thry claim is clearing our water for it to be safe and the bottled water was 32 so i can say it definitely works
