Couldn’t understand the instructions nor the readings. Returned and bought a more expensive one that had ‘normal’ readings!

Don't trust this trash for anything. pH calibration literally never works, and pH will bounce around WILDLY reading from 4-8pH during any reading or calibration. TRASH.

I used this for work testing water quality and commercial filtration system calibration/function while repairing high-end espresso, coffee, beverage machines. The app and Bluetooth functionality came in handy for record keeping and spotting patterns when having repeat service calls at a location.

Really simple, straight foreword, easy to calibrate, easy to access the batteries.It’ll do the job as well as the 100 dollar one…

It's what you'd want for a better than super cheap tester, no issues and has consistently functioned accurately for me.

Not worth the money spent on this. It needs to be calibrated all the time and it’ll stop working within the year.

Forget all the other types of PH testers, buy this one for accurate reliable results.

Purchased my first meter in May 24. When measuring pH, meter would start jumping around by like .5 at a time, other than the gradual sweep I normally seen. Messaged Vivosun and they credited me a new one. Very good product with excellent support. Worth every cent. Biggest bang for the buck you will ever find. Thank you Vivosun for your attention to detail.

Vivosun stands behind their products. I used this meter for 6 months and it quit working. Customer Support refunded my purchase price. So I bought another. Accurate measurements. Excellent tool at a very good price.

As far as mid-range ph meters this is a decent meter. I had decided to upgrade from the black and yellow ph meter to this one and when compared its night and day. This meter has a backlight which I love it came pre-calibrated off by maybe .1 or .2 nothing that would really effect anything when re-calibrating was super easy with RO water. I tested this side by side my cheap black and yellow (11 dollar) ph meter and could deffinatly tell i needed a upgrade the black and yellow would be completly off even after re-calibration this one held calibration through and through even after doing several ph readings with diffrent liquids and water no issue. the PPM I couldn't really tell as I compared it with the blue reader ( cheap one) and came out basically the same so I can assume its accurate out of the box.

Accuracy was good for about 60 days. I’m sure I got a defective one though. Now my pen will not calibrate.. Hopefully they honor the warranty. I will up date.I emailed Vivosun and they sure did send a new one. I’ve bought multiple products from this company and they stand behind the warranty’s on their products. Super easy warranty claims. I have an older model PH meter that i bought 2 years ago and it is still supper accurate.
