TDS Meter, Electronic Water Tester with 0-9990 PPM Measurement Range, Hand Held Digital Water Test Pen for Farming, Aquariums, Pools, Household Drinking Water (Blue)

Thank you for selling this separately as we lost the one that originally came with the kit.

Was a replacement for my old Zero Water tester. Works well.

Quickly gives a reading on water quality.

I have an expensive water system in my house and I was shown how to test for safe drinking water. I purchased this monitor as recommended and it works as well as my water companies. I have actually shown several of my friends how bad their drinking water is which they did not believe until they saw my results and they have a cheap filtering system. Most tap water here in the US is actually not safe to drink unless you have a really high grade filtering system which is worth every Penney .

Replacement for my 4 year old zero water TDS meter. Works as described

Had one just like this for a few years. Till I dropped into on of my aquariums. This one is just like the one I had. Would buy again

May be excellent, but I have never had need to use it.

I just bought my third TDS meter.

I purchased this TDS Meter to mix RO water with tap water for my aquariums, and it has been a fantastic addition to my toolkit. The device is highly precise and provides quick, accurate readings every time. It's easy to use, and the measurement range is perfect for all my needs. I’m extremely satisfied with its performance, and it’s a must-have for anyone who needs reliable water testing. Highly recommended!

It couldn’t be easier or faster to get an accurate reading. Seems robust & good value 🤩💦

The TDS Meter is a handy tool for quickly testing water quality. The 0-9990 PPM measurement range is more than sufficient for household use, whether for drinking water, pools, aquariums, or even farming needs. I’ve found it to be accurate and consistent in its readings, which gives me confidence in monitoring my water.It’s lightweight and portable, making it easy to carry around, and the digital display is clear and easy to read. I also appreciate the straightforward instructions—it’s simple to use, even for someone new to water testing.The reason I gave it 4 stars instead of 5 is that it doesn’t come with a calibration solution or case, which would’ve been a nice addition for maintaining accuracy over time. Overall, it’s an excellent device for its price and purpose. Highly recommended for anyone who needs a reliable water testing solution!

Did some tests. Our tap water is 250 ppm. Filtered once in the Brita jug, 130 ppm. Filtered twice, 91 ppm. Filtered 3 times, still 91 ppm. Rain water, 51 ppm which is expected as it has low mineral content.

Bought to replace the one on my zero water filter. Does the exact job it is suppose to do.
