2025 All-New 4 in 1 Tds Meter Digital Water Tester - Accurate and Reliable TDS EC & Temp(°C,°F) Meter - 0-9999ppm - Professional Testing for Drinking Water, RO/DI System, Aquariums etc

Works well. Used it a couple times. Easy to use and battery’s seem to last. Gives temp too

Wanted mom to drink my filtered water I get from my rain barrel and clean. Said store bought is better. I got several layers of filters to clean it more and she said no, but dad loved it. Then got a UV-C light to get 100% comfort on disinfection. Mom still said no.So got this to prove the cleanliness of the water and checked a bottle of water and got 34. Wells within 0-50. So I tried my water at various stages of clean. After the initial screens and uv-c light. It’s already 14-16. Add the extra filters and a pass through a brita filter and down to 11. Mom still not convinced hehe. Even aunts distilled water was only down to 7. So thought “let’s check the well water too!” Big mistake as the screen turned dark red as it displayed 1760 and basically told me to run.So really cool and seems to work really well, didn’t even realize it had a temperature control feature, but the readability of the screen and size of the device are really nice and helped give me more comfort in my drinking water.

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

Functionality, brightness, accuracy, quality it’s all there

Works great. No issues. Decent quality. Functionality for the price well worth it.

Really easy to use and very accurate. I like that it measures TDS, EC, and temperature all in one. The screen is clear, results show up fast, and the auto shut-off is super handy. Tested it on tap and bottled water and the readings were spot on. Great value for the price

So I purchased this for aquarium use. You get quick readings when testing the TDS. I tested my tap water which came in at 30-34 ppm, which is the range I expected since I know for a fact that San Francisco water is known for good clean tap water and always drink it. I then wanted to test the temperature readings and it didn’t work at all. Cold water or hot water, it just gave me one reading. It only fluctuated once by one or two degrees from cold water to hot water. If it can’t get a simple temperature reading then I question how reliable the TDS reading actually is. I’ll probably buy a different meter to double check the accuracy because for now I can’t really trust it.

Easy to use. It seems to be accurate, although it would be difficult to know for sure unless you test it against other water testers.
