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 am impressed, I noticed the water coming out of my facuet seems to leave stains that are hard to get rid of. Just to think that's the water they say is safer a better than store bought. I got the tester to see if I would get the same reading in store bought and tap. I got a reading of 154 from the tap and store bought readings in the single digits. I would pour into a cup then empty then pour the other source. I always get the high reading for the tap vs the store bought. Which proves what I was thinking all along they are not the same. Just for the fun of it I tested Vitamin water and got a reading of 1800!!. I saw in a previous review that the tester is reacting to the minerals. I hope that's true or I have been drinking some super contaminated water for a long time!!.

It arrived on time. It does have the readings on the back that you can compare it to. I tested it right away. I did my tap water, Poland Springs bottle water, and I did my purified water that is in my refrigerator. So results came out tap water 41, Poland Springs water 61, and my purified water that was in my refrigerator was 0.I tested a few times in different order to see if it would read differently, and it was the same.I would recommend this product to anyone who wants to keep an eye on what they are drinking.I would purchase this product again.

I don't have the means to judge the accuracy, but when I tested tap, filtered (Britta) and reverse osmosis filtered water, the results were as expected.It takes just a few seconds to run a test, and the device is incredibly inexpensive, so I'm happy with it.It's a must have if you are using water filters.

I’ve been using the 2024 All-New 4-in-1 TDS Meter for a few weeks now, and it’s proving to be a great little tool. It’s easy to use straight out of the box, and I appreciate the quick, accurate readings for TDS, EC, and temperature in both °C and °F. The digital display is clear, and switching between modes is seamless.I’ve tested it on my RO system and it gave consistent results across multiple tests — definitely feels reliable. The auto shut-off and hold functions are also thoughtful additions

TDS meter works well for my home shrimp tanks. So far, it seems to be accurate. I measure distilled water pretty often to double check my meter and it’s been 0/1 every time. So I feel pretty confident in the readings I’m getting for my tanks.

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.

Bought this as I wanted to test my drinking water. Easy to use as result is very quick. Glad I found out my water as not as good as I thought it was.

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.
