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 think nowadays it’s important to know what’s in your food and water so this is a must. The things they’re allowing to be put in our food and water are insane. This is easy to use and read. Great value. Works well. Good size, not bulky like others. I’m sure there are more expensive accurate ones but this one does its job. Makes me feel better testing my water to see which one is best, especially bottled water & my sink water. I highly highly recommend.

Fantastic product - provides temperature and EC in an instant, just turn it on, put it in the water, between the two lines, wait 5 seconds and you get your results. It is small so doesn't take up space. It is made of plastic but the plastic is of good quality, not thin or flimsy. I would highly recommend if you have a hydroponic system or aquarium to have one of these so that you can easily test the water.

Nice device. Attractive, consistent readings. Looking now for an accurate liquid calibration solution.

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.

This is very accurate, works well, is easy to read, you need one these for every house were your drinking tap water, you'll be amazed at what it shows is in your water

I am a health enthusiast. This little gadget is amazing and easy to use.We tested our tap water and already knew it wasn’t healthy but this tester proved it is indeed bad.Easy to carry when traveling or going to restaurants!

This works great! Quick and accurate. Handy thing to have to check the water you’ve been drinking.

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.
