I want to start by saying I really do love all of my Hanna testers! I have a question about my pH tester right now. I have the “Hannah checker plus” – the red one? It is calibrated to seven. How long do I need to leave it in the water before that hourglass stops. If feels like I wait forever with it in the water. And the levels continually bounces back-and-forth? Do I not have a calibrated correctly? Or am I just not that patient[emoji848]

Slow and steady wins the race!
The flashing hourglass time seems to vary on my checker but I hold it in water until it stops. I also will shake the probe while it’s submerged to dislodge any bubbles for a more accurate reading.
