This TDS meter is the next generation for today's tech-savvy and health-conscience consumer. If you have a reverse osmosis system, how do you know when to change the membrane? The answer is "You don't... unless you have a TDS meter." Everyday we are shocked to hear people ask if their membrane should be replaced and they have no idea of what their water quality might be. A TDS meter to measure your water quality is as important as the Reverse Osmosis System itself.
Overall rating: 4.5 / 5 from 14 reviews.

"I have found these TDS meters to be reliable and accurate. They are being used as a back up in case an onboard TDS meter fails. I am thrilled to find these meters are made in the USA! I have one in my emergency backpack for testing water wherever I go. They use a very common easy-to-replace battery. I highly recommend these meters as they are super easy to use and to read."

"Easy to use. Works as intended. Helps monitor how effective our new reverse osmosis is, and when the membrane needs to be replaced."
— Jennifer S. (5/5)
"Believe it or not it is extremely hard to find a TDS Meter made in America, after doing some research i went with the US Water Systems (TDS-3), it wasnt the least expensive but it is made in America and has very good reviews. The meter quality appears to be good, it is very easy to use with complete good instructions. US Water Systems communications were excellent and shipping time was very good."

"Best I have found."

"This TDS meter works great. The thing that surprised me was that it registers exactly the same score as my whole house reverse osmosis system registers. I think that proves its accuracy."
— Damon, J. (5/5)
"Terrible...."
— Philip C. (1/5)
"Makes it very easy to check quality of my drinking water"
— George R. (5/5)
"This test kit is 70% cheaper than Lamotte test kits which are supposedly the best. This test kit is almost the same for 1/3 of the cost."
— Philip B. (5/5)
"The instructions that come with the device needs some work. It really doesn't describe how to use it, what the Modes are, why take the temperature, how to clear to zero, and much more. The videos only answer part of these questions and I keep getting sent to the same video."
— Fred S. (3/5)
