I have these ph strips. The instructions say “read immediately”. The word “immediately” is in bold.
When I’m looking at them after dipping into a solution they rapidly darken over about 7-10 seconds. Do I read them in that first second or two/three or is the value after say 7-10 seconds more accurate?
Not sure what precisely “read immediately” means.
