Yep it's a brand new apera pH 60....my vivosun and apera are both the same pH %...it's not the pens!!!Have you calibrated your pH pen?
Yep and calibrated my vivosun and they both came out the same...I have a ph60. Have you checked it with all 3 of the calibration solutions? My original ph60 was defective...
You have the same apera as me. I calibrate at least every month or if it’s been awhile… at least there’s verification of your reading.Yep and calibrated my vivosun and they both came out the same...View attachment 1459315
Yes now I know it's not my pH pen??? Has to be water or soil!!!!You have the same apera as me. I calibrate at least every month or if it’s been awhile… at least there’s verification of your reading.
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 problemsYep and calibrated my vivosun and they both came out the same...View attachment 1459315
