Prestige PH Meter
First pen had an issue during calibration, called the Growace team, they replaced it right away, and the new one has been working great !
This PH pen meter comes with a sample of calibration fluid and does the job so far, no buffer fluid included to re-calibrate the meter.
delivered on time and is very accurate.
