pH Meter: How long to get a reading?
One thing I wasn’t expecting is that it takes about 2-3 minutes to get an accurate reading. When I first insert the probe, the initial reading is usually around 7 or 8, and then it slowly starts going down until it eventually settles at the final reading. I have found that gently stirring the probe in the sample speeds the process up a bit and actually seems necessary to get an accurate reading (as confirmed with testing solutions).
