They work good if you do it correctly and I would definitely calibrate the ph pen before use.

This set has a pH tester and two TDS meters, one is meant to be a quick, portable tester. All of these are easy to use and work fine, they are great for testing tap water or your fridge water filter. I like that they give you the calibration powders for the pH meter, this could easily have been omitted at this price point. Please note that you're supposed to rinse these in distilled water after using.NOTE: My rating system is as follows:5 star: I would buy it again and recommend to my friends4 star: performs as advertised3 star: performs as advertised with some exceptions2 star: not very good1 star: product is terrible and possibly dangerous

I’ve been using this fantastic 3-piece water testing set for a while now, and I’m genuinely impressed with its value and performance!My favorite of the trio is hands-down the TDS tester. It finally settled a long-standing debate between my father and me about aftermarket Zero Water filters. Turns out, he was right—the aftermarket filters perform just as well as the pricier originals. This revelation is already saving me money on filters moving forward, and I couldn’t be happier with the TDS tester’s clear, reliable readings.The pH meter is another highlight. I love that it came with three calibration powders, making the process straightforward and hassle-free. After calibrating, I tested it against my pool pH meter (professionally calibrated at the pool supply store), and the accuracy was spot-on—definitely a win for home testing! The 0.01 precision on the digital pH tester is a nice touch for anyone needing detailed results.The only minor hiccup I noticed was the temperature reading on the TDS meter, which was about 0.5°F lower than two high-end water temperature testers I own. It’s a small discrepancy and far from a deal breaker, especially for my needs, but worth noting.For the price, this set is an absolute steal. The combination of a reliable TDS tester, an accurate and easy-to-calibrate pH meter, and the included calibration powders makes this a fantastic deal for anyone monitoring water quality—whether for drinking, pools, or other uses. Highly recommend this budget-friendly, effective kit!

Nice set of 3 instruments.Each for a specific task.I liked itI wish they had a case of some sort.Hard to not loose one this way.Price: reasonableBatteries: not standard batteries. I wish they used regular AAA batteries or USB rechargeable ones. So costly to maintain in long run if you use the regularly

What I really needed this meter set for was the TDS and the pH meter. I’m unfamiliar with the 3rd one although maybe it’s useful if you need a water temperature. Unsure what the EC is for. I was thinking maybe fish keepers use this, but as you can’t submerge it, I can’t see what the value of taking the temperature at the very top of the fish tank would be. I’m only giving this review three stars because technically, I only am getting value from the TDS meter. The pH meter is kind of horrendous. It is supposed to tell you the pH within 30 seconds. It does not. It is sooooooo slow that by the time you get close to the pH value, the display times out shuts off. When I first tried it out on tapwater it registered 14. I assumed my water was so alkaline, I shouldn’t be drinking it, OR that the meter was not calibrated. It does come with a calibration buffer solution kit so, I went and got some distilled water and tested it again. It did register 6.99, but it took about an eternity to measure it. It also timed out twice. The only way I finally got a measurement was turning it on and off immediately after it timed out so that the monitor was already in the 7’s. I tested it immediately thereafter in municipal tapwater and it register registered 7.44. This seems pretty accurate to me, but I can’t fathom the application of a meter taking this long to provide a measurement. Not sure if it’s user error or a bum device. Just sharing my experience. The TDS meter is great, however, and I’ll be using this to gauge when I need to replace the filters in my reverse osmosis countertop water filter. If that’s all you need, this is a great kit and it’s pretty reasonably priced overall, but she could probably get a standalone TDS meter for less.

Just got this 3-in-1 TDS & pH Meter set a week ago to use with my hydroponic setup, and I’ve already put it to work more times than I expected. I’ve dabbled with those cheap pH strips before, and finding out whether my water was actually balanced felt like rolling dice. With this digital tester, it’s way less of a guessing game. The readings are super quick and honestly, seem spot-on every time I double check against my reference solution.Setting it up was pretty straightforward, even for someone like me who can barely keep basil alive. The kit comes with three pH calibration powders, which was a plus because I’d never calibrated anything in my life. The instructions weren’t intimidating at all, so I had it ready for the first round in ten minutes, tops.Biggest win so far? Catching an off reading before topping up my hydro reservoir. I adjusted things right away, and my plants have perked up since. The device feels sturdy, so I’m not worried about breaking it whenever I pull it out for my “science experiment” routine.Haven’t had it long, but if these results keep up, this is going to be one of those tools I reach for every grow. Very happy with it and honestly wish I’d upgraded sooner. If you’re doing any kind of water testing at home, this thing works, plain and simple.
