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.

### ⭐⭐⭐⭐⭐ Easy to use tool

Looks great, easy to keep clean, seems accurate, everything I was looking for

### ⭐ Good luck w/ recalibration
*by H***R on February 6, 2026*

Meter comes w/ single use buffer packet used to calibrate the meter. Meter requires periodic recalibration. But the company does not disclose the contents of the buffer packet nor where they may be purchased. Not in the instructions and not on the company website. Indeed, instructions say to contact the company if there are any problems but don't disclose any contact info at all. So if you buy this meter it will be good until it needs recalibration then it's just another piece of useless junk. This meter does not appear on the company website at all. Take a hard pass on it.
