SM21-AG4横河PH电极

日本横河SM21-AG4 PH电极

■ Overview

The most crucial component of the pH measurement loop is the pH-sensitive measuring electrode. Yokogawa has developed a range of electrodes to ensure the best performance in each application. 

The components of the measuring loop and their important qualities must be understood to select the right glass electrode for a given application. A choice must consider both the mechanical design shape and the chemical composition of “pH glass.” 

For most pH applications, the ball-shaped type (shockproof) will offer a fast response and high sensitivity. 

The heavy-duty dome-shaped type has an incredibly robust pH membrane that offers a high chemical resistance type. It ensures a long sensor lifetime and strong chemical resistance.
