Ask An Expert - Overtitration and Ultrameter III 9P

[Myron L Meters]

(Re: Ultrameter III) May I ask what happens if you overtitrate? Or how the instrument at all knows how much you have inserted? I do not see any form of input for the user. Sorry to ask this but the practical part is still a bit of a mystery to me. It sounds very much like the accuracy of the titration is highly dependent on what the user does, or am I mistaken in this matter?

The 9PTK instrument measures alkalinity using a conductometric titration method. You must titrate the reagents into the meter. Simple user-intuitive prompts walk you through the entire process so there is no confusion. It will display an alkalinity number instead of giving you a color to guess.
