pH testing question
« on: July 07, 2012, 03:39:10 AM »
the ph probe im measuring with has no "stabilizing" bar, so i have to wait for the reading to stabilize.
roughly for how long should you wait till the reading is at one reading without changing?

You have to watch the result and wait till it stabilizes, there is no other way. If it doesn't stabilize - you are out of luck, there is something wrong with the pH meter or the electrode.
