Digital PH Meter, pH Tester 0-14 PH Measurement Range for Household Drinking, Pool and Aquarium Water PH Tester Design with ATC, High Accuracy Water Quality Tester

The meter arrived very fast and as described. It also comes with directions and calibration standards, but it doesn’t say if it needs calibrated straight out of the package or after a battery change or if you just think it needs it 😊 but I’m happy with the case and product and display.

This a pretty cool divice. Now I can test my water to see for myself what I have. No more taking water samples to the water place. Very easy to use.

Complete and utter waste of money I had a friend bring it to me from the US and I filled the exact instructions for calibration the buffers are useless as they dont dont give you the right ph. And the best part is it stopped functioning on the second day. Cant really refund it replace as I live in pakistan. Dont be fooled by the prices its complete bullcrap.

Works as advertised. Will just have to wait and see what the battery life will be like.

1st one Wouldn’t turn on, so I checked the batteries but that wasn’t the issue, returned it got a second one, Second one was glitchy and would not function correctly. Wasted almost a month without a pH tester, I’ve been guessing thus far.

Reading never stop moving I even replace my product still did the same. I would not recommend recalibrate several times over not worth it.

The ph meter only says errDoesn't work at all

Just got the ph meter pen and I followed the steps and it reads error every time I try to collaborate.
