I have a ph60. Have you checked it with all 3 of the calibration solutions? My original ph60 was defective...
Yep and calibrated my vivosun and they both came out the same...

Have you checked the PH of the RO water after letting it sit open to the air for a day or two?

You could resort to real science and send a sample to a lab for agricultural analysis ?

Calibration solutions are 4.0, 7.0 and 10.01 and neither of yours is reading any of those. It's definitely off... Recalibrate using all three of the solutions and little jars it comes with. The defective apera I had would always be 0.2 off even after calibration causing me to constantly pH down without needing to and causing all sorts of problems
