Worth trying!
I recently purchased the TDS Water Tester, and I have to say, it's been a game changer for monitoring my drinking water quality. This handy little device combines three essential functions: it tests Total Dissolved Solids (TDS), temperature, and pH levels. As someone who is increasingly conscious about water quality, this feature-packed tester has made it easy to ensure that the water I consume is safe and clean. The design of the TDS Water Tester is sleek and user-friendly. It fits comfortably in your hand and has a clear digital display that makes reading results straightforward. I appreciated how lightweight it is; it's compact enough to carry in my bag or keep on my kitchen counter without taking up much space. In terms of performance, the accuracy of the readings has impressed me. The TDS measurement gives me a good indication of how many dissolved solids are present in my water, which is crucial for assessing its purity. Additionally, being able to check the temperature and pH level in one device is incredibly convenient. I've used it on various water sources—from tap water to bottled water—and the results have always aligned with what I expected. As for the price, I found it quite reasonable considering its multi-functionality. It’s an affordable investment for anyone looking to improve their hydration habits and overall health by ensuring their drinking water meets quality standards. User experience has been smooth as well; it's intuitive enough that even my family members can use it without needing a tutorial. The instructions are clear, and getting results only takes a few seconds. Overall, I would highly recommend the TDS Water Tester to anyone interested in monitoring their drinking water quality. Its combination of features, ease of use, and affordability makes it a must-have for health-conscious individuals or families. This little gadget has given me peace of mind about what I'm drinking every day!

Great product!!!!!
Accurate, Easy to Use, and Super Handy! I bought this TDS water tester to check the quality of my drinking water, and it’s been such a helpful little tool! It arrived quickly, was well-packaged, and came with a protective case and clear instructions. What I love most is how easy it is to use—just dip it in the water, and within seconds, you get an accurate reading. It’s been great for testing tap water, filtered water, and even bottled water. It really opened my eyes to how much residue is in some water sources! The digital display is clear and easy to read, and the auto shut-off feature helps preserve battery life. It’s also compact enough to carry with me when I travel or visit family, so I can test water anywhere. If you're serious about your water quality or just curious, this tester is a must-have. Reliable, affordable, and surprisingly fun to use—highly recommend!

A valuable aquarium tool
I’m hard pressed to say it’s required but getting this is valuable for tracking the health of your tank for pre and post water Changes or if the water is seeming “off”. Helpful for seeing if the filters are in proper operation long term as well if your tds starts to grow more steadily. Operation is simple, turn on and dip. Can hit the hold button so it keeps the measurement on screen or it will zero out once it’s out of water

If you’re looking to measure TDS, this is your girl
This little thing was super powerful and did the job. My daughter did a science project where she had to measure the TDS and various water sources, including rainwater. I was quite surprised by the different readings from different tap sources in our house versus our water purifier, and all the other areas that she collected from around the community. It was a fun project. The device was super easy to use. I wish I had more functionality, but it only does the one job, so if that’s what you’re looking for it’ll be great. If you’re looking for more by a different unit.

I recently purchased the TDS Water Tester (Deep Blue) to check the quality of my drinking water, and I couldn’t be happier! The device is lightweight, portable, and incredibly easy to use right out of the box. It gives quick and accurate readings within seconds. I tested it on tap water, filtered water, and bottled water — the results matched my expectations and helped me feel much more confident about what I’m drinking. The screen is clear and easy to read, and the auto-off feature is great for saving battery life. Plus, it comes calibrated, so there’s no need for complicated setup. For the price, this is an excellent tool to have at home, especially if you’re concerned about water quality. Highly recommend it for anyone who wants peace of mind about their drinking water!

TDS limit for after RO treatment.
This meter does not have a color table on the back to indicate the TDS ranges for RO water, Distilled water, bottle water and EPA max allowable drinking water limits like old meter.
