2025 Newest 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 tried it and it's very easy to use. Changing battery is easy too. It takes a Flat battery (idk what their called tbh but it's almost the size of a dime)

Nice gadget to have. I use this a lot to check the water I use on my camping trips.

I have a water softener here in Jax, FL and I bought this so I could see if the system was actually working. Lo and behold it has shown me that it’s actually not working and it’s not making my water very soft at all. Needless to say this product has given me great insight into making sure I get the company to fix my system or give me a new one since I spent roughly $5,000 on it and I’m being cheated. If you’re having doubts, get the tester since it works wonders. This was take. Right out of my fridge dispenser and I tested it to a bottle of Poland spring water and the results were obviously night and day

I use this for my Zero Water Filter setup and is a quality product for the money it has a hydrophobic surface that makes it easy to get the water off for storing after testing water

Awesome

as a pool & spa professional - knowing EXACTLY where the water chemistry is at is crucial - I could not do my job well without this!!

Works great but battery cannot be replaced.

You should know what kind of water you are drinking. If you don't check it you may be drinking toxic water. Get a tester now.
