VIVOSUN Digital pH Meter 0.01 Accuracy Pen Tester for Water Hydroponics | ±0.01 pH Accuracy, ATC, Auto Calibration, Backlit LCD, Memory, Compact, UL Certified, for Hydroponics Aquarium Pool Drinking: desertcart.com: Industrial & Scientific

Review: Recommend. Much better than the ph strips - This product works as advertised. You have to calibrate it first using the provided ph packets but once you do that it is good to go and offers accurate reading. This product assembly and price range makes for a nice introductory ph meter as opposed to a more premium, and also costly, assembly, yet it is still so much better than a manual ph test strip. I would recommend this product to anyone looking for an affordable digital oh tester. I like the vivosun brand and the products they have offered so far.
Review: Inexpensive, but good PH meter. - This is the second of these PH meters I've purchased. There are a number of negative reviews, so I was a little concerned but went ahead and order one. The first meter calibrated easily and (apparently) accurately. I used the three point calibration, then tested my fish tanks and compared the reading to the drop type ph test kit I had been using. It was spot on as close as I could tell with the test kit. I used the meter for a week, every day on several tanks as I changed the ph. It tracked these changes as I would have expected it to. It worked very well for me so I ordered a second PH meter. (I have fish tanks in two locations.) I then used these two meters side by side. They vary from each other by 0.10 points. The second meter did not calibrate as easily as the first, and the calibration was off slightly. I will try recalibrating, but it's as accurate as I need now. I'm very satisficed with them and would recommend.

## Questions & Answers

**Q: What do you use to clean electrode?**
A: Instructions say to use distilled water to clean electrodes

**Q: Would this be a good tool for an aquarium?**
A: Sure it will read the Ph for your tank

**Q: Does it work well for testing ph in a saltwater pool?**
A: I don’t know anything about testing pool water but it will definitely give you the ph between 4.0-10

**Q: My pen has gone way out of calibration. Is there a way to calibrate it against an accurate test kit? I.e. just set the pH?**
A: I second the answer but Alix. I thought it could be recalibrated against the standards they provide and I would be back to using the ph tool. Once it started to give me bogus readings I knew I had a new paper weight. I even bought 7.0 fluid so I could check it before each use so I knew the readings were correct. I have extensive experience calibrating thousands of gauges in a railroad machine shop to NIST and audited by the ARR annually. Knowing I have a good accurate tool is important to me. The quality of this tool is below the mark. I am surprised as I own VIVOSUN products that are more reliable so I thought I would give it a chance. It lasted almost a year for me.

### ⭐ Save your money. Buy another product!
*by M***A on August 28, 2026*

Please understand I rarely give reviews but I felt led to warn potential users. It simply will not calibrate. I have received multiple errors. I've gone through the trouble shooting steps and still no success. Changed the batteries, rinsed it with plain water to retest, made sure I didn't go over the max line, turned it off/on and I even measured the water to 250ml. Frustrating to say the least.
