Review: Appear to work well - After reading several reviews on this and other similar models I decided on this two pack PH and TDS. I recently installed a reverse osmosis under kitchen sink with a tds digital display and wanted another way to check its accuracy along with what ph the RO water was putting out. Item arrived quickly and after reading instructions I decided to give it a test. Batteries were already installed and additional batteries were included so that and they both were already calibrated so two pluses from the start. I filled a glass with reverse osmosis water and another from bathroom sink. Tds for bathroom were 107 compared to RO water of 9. This is the same reading my RO system shows so I assume its pretty accurate. Next I tested the PH. Ro water was higher than bath sink water but this units numbers jumped around a bit. Although the numbers did not display steadily i was able to get a good reading and am pleased with the results. For the price I find the two units a great bargain and much better than the water test strips I was using. After my initial tests I highly recommend these products as they appear to be accurate and easy to read.
Review: Great value for a reliable meter! - If you’re looking for an affordable way to check pH, TDS, and EC without spending a lot of money, this is a great option. It gives you several useful readings in one device and is much more convenient than buying separate meters. The readings have been consistent for what I need, and the auto-calibration and temperature compensation make it easy to get started without a lot of messing around. The display is easy to read, and having the hold function is a nice bonus. For the price, I really don’t think you need to spend more unless you have a specific reason to buy a higher-end professional meter. This one gives you the important functions at a fraction of the cost. Definitely one of those purchases where you get a lot for your money.

### ⭐⭐⭐⭐ Do not buy these.
*by D***. on May 27, 2026*

Updated review: They work pretty well. You must calibrate them! The tds meter was way off and it doesn't come with calibration powder. The pH does. You can make 1 cup of each solution and store it for later use (I assume. I have saved it for later but only calibrated once so far) I bought this set as a backup. I dropped my main ph pen and broke the tip so I've been forced to lean on these. I calibrated the tds meter using my main tds meter and it's off by about .015 or so and that's good enough. The pH meter so far has been pulling it's weight.
