- PH Tester Digital, 5 in 1 PH Meter for Water/Salinity Meter/tds/ec/Thermometer, Pool Salt Tester with Constant Temperature Compensation, Suitable for Drinking Water Swimming Pools Aquariums

I’ve been using this handy tester for my hydroponic garden, and it’s been fantastic. It gives fast, accurate readings for pH, TDS, EC, salinity, and temperature, which helps me keep my nutrient levels perfectly balanced. The constant temperature compensation ensures my readings stay consistent, even when my water temp fluctuates. It’s easy to calibrate and the display is clear and easy to read. I'm getting serious about hydroponics and this is a must-have for keeping my plants healthy and thriving.

I did not buy this tool to measure my pool water but rather to test the water quality of water coming into my house and to help maintain my hydroponics vegetable grow. I tested it against a known accurate meter and they both read the same for PPS, EC and pH. I like the easy to ready readout and it appears the 3 LR44 batteries are easy to change. I looked at several other meters that look identical to this one and most are listed as IP67 waterproof. This one has rubber o-rings so I think it's safe to say it is probably also IP67 waterproof.

I have had two of these and have been using them for two years. PH measurement is sufficiently accurate and very convenient. Also, you can always recal if you want. Salt measurement is crap. It was accurate when received but went south pretty quickly after use.

Pretty cool water multi-tester. I am pretty concerned about water quality, so I have multiple water testers for different applications including PH, TDS and Salinity, but Pious tester has all these features built into a single device. Having a temperature tested in a good to have feature. I've tested it vs. my other devices and it seems to be pretty accurate in terms of metrics. Very fast reading, great functionality, compact size. Great value for the money.

Excellent device for monitoring water quality. I purchased it mostly to monitor my drinking water as well as my fish aquarium. It is easy to use, compact enough and provides accurate results in seconds. Comes with calibrating powder if needed. I have not yet done calibrating, but found some videos online to help with this.

I am new(ish) to pool maintenance. I had a "pool guy" doing my pool since new about 2 years ago and just decided to do it myself. I knew enough to know that I needed something a little more exact than a color on a test strip that I match to the color chart on the test strip bottle. Since I have a salt water pool I also wanted something to test salinity. This 5 in 1 digital tester and the test strips give me the confidence to make sure the results I am seeing is the actual condition of the pool water. I really want and like my pool being as clear and clean as possible and with this digital tester I can do just that. The one thing to remember is that if you have a salt water pool, you don't need to read the TDS as the "free salt in the pool will be considered a part of the TDS reading. I like salt water pools as they make my skin feel better than a traditional chlorine pool. Would I recommend this 5 in 1 tester to friends and family? Yes. This tester gives me the confidence that I am making or should I say deciphering the test strip results correctly and with this tester, I am more accurate than just test strips alone. As an added extra benefit, I use the TDS reading for my car washing. Using the TDS meter for my car washing helps me to make sure my rinse water is free of "solids" that will cause water spots.

Junk Worked twice- readings were verified and close enough to controls to accept. Put back in box in cabinet- made changes to home water system and used tester to verify- pH Readings for all water samples ( municipal with and without home filtration) are in the 3’s. Additional testing verified water ph is our normal range 7-7.5. Another cheap product to clog up the landfill

Wanted a quick way to test water for my aquarium. Simple to use and accurately measures TDS, pH, and temperature. I tested against another digital meter as well as API test kit and they all came in very close for the readings. Measurement readings for TDS and pH fluctuates slightly and is slightly slow taking a few seconds to settle at a general reading, but I assume it’s always calculating the small changes in real time. The one thing I don’t like is it uses three LR coin style batteries which can be expensive. The meter is bulkier than just a standard TDS meter so a standard AA or AAA would have been nice. Other than that, the meter is a nice way to get several readings at once without fiddling with other tests.
