So KCl is extra for making a legitimate pH measurement like a A part of the Drinking water Conductivity - Phase 3 exam. The increase while in the ionic toughness is required so that there's small focus gradient across the pH electrode diaphragm/junction. A large concentration gradient brings about a lack of equilibrium and unstable pH reaction.
). For Computer, you have an interest in the caliber of the water in the system powering the valve and do not want contamination in a sampling port to bias the interpretation of the data.
