## Description

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: Meter Accuracte down to One tenth - Although it may be a little delicate to calibrate upon first time using. Insure solution temperature is ~75 degrees F. Measure out 250 ml distilled water. Insert the meter into a cup pour into another cup until you reach the line on the meter. Turn meter on holding down the calibrate button for 5 seconds then release. Press Cal button one more time. I did not get a display showing "cal" like some of the YT videos. This generates confidence in the meter concerns. However, I had a lab tech at the university check the calibration in a buffer solution of 7.0 and the meter showed 6.97. First pH meter that works and provides accurate results.

## 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.

### ⭐⭐⭐⭐⭐ Meter Accuracte down to One tenth

### ⭐⭐⭐⭐⭐ Ph test
*by C***B on July 25, 2026*

Works great

### ⭐ Sometimes things are cheap for a reason
*by T***R on July 28, 2026*

Sometimes there’s a reason something is unusually cheap. Bought this $10 version while the next cheapest were all $30 or more. Now I know why. Didn’t work at all, right out of the box. I’d call it a toy, because it was junky and plastic, but a toy would work better. Save yourself a step and buy a $30 version - like I am getting ready to do now.
