1.General Introduction
Yokogawa SM21 PH electrode is a single glass type with G and L type selectable, G glass sensor is for all general applications, L-glass sensors is for high temperature chemically harsh applications with maximum working pressure up to 10bar, dimensions and design meet the requirements of DIN 19263. The selection of the correct type of glass electrode depends on both the type of glass membrane thickness of the glass membrane, and dome shaped membrane for “Heavy Duty” applications.
