Digital pH Meter

Can anyone recommend a QUALITY digital pH meter? I bought this one and the readings are all over the place each and every time I use it.

Also - it needs to be rinsed w distilled water each time it is calibrated. Who has that laying around??? It's just a total pain to use.

I'm REALLY bad at seeing colors - I wore a brown sock and black sock to work one day - so my Taylor test kit just doesn't work for me for pH testing.

I have been using this for the past year and have had good success. It's accurate and easy to set up and read. https://www.amazon.com/Apera-Instruments-AI311-Replaceable-2-00-16-00/dp/B01ENFOIQE

I just bought this. Never calibrated and don’t rinse in distillled water. Seems fine so far. Only had it 2 days but used it about 6 times including before and after adding borax. Under $10

I have the Apera PH60. Love it. Comes with calibration fluids and easy to do. I do rinse it in distilled water which I purchased at local grocery store. I put some in a squirt bottle and easy to rinse the meter.
