The pH meter clearly recognizes the lower pH of water from reverse osmosis filtration. I am not able to verify the precision of the values, but they seem accurate based on my knowledge. The build quality is solid. Please note that batteries are not included. I would definitely buy another one as it offers good value for money.
The estimated delivery date initially provided was two weeks later than the actual arrival date, which was a pleasant surprise. Good job Banggood!

Q:
does it have to be calibrated every single time before using it?
does it have to be calibrated every single time before using it?
No it does not need to calibrate it every time I have been using one for about ten years and
I only calibrate it every 4-6 weeks unless you drop it or knock it hard then it will need to be
recalibrated again
Hope this helps
