SM23-AN4工业电极

日本横河SM23-AN4工业电极

■ Overview 

The SM23 is suitable for long term, reliable Sodium ion monitoring. Another application is to use the pNa sensor as reference electrode for pH measurement in combination with an analyzer with dual high input impedance specification.

This may considerably save maintenance costs in application where the salt content is constant, and the pH is 2-3 units higher than the pNa value. pNa measurement is used in many applications, but the most frequent applications are found in pure water applications, where Sodium is measured to detect carry-over of salts in steam, leakage of salt through cation filters, leakage of salt from leaking condensers. 

Other applications where the pNa electrode is used for measurement is in brine solutions.
