SM23 single pNa electrode

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

This may considerably save maintenance costs in application where the salt content is constant and pH>pNa+2.

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. Please note that accurate measurement requires that the pH is 2-3 units higher

than the pNa value.

Features

• Dimensions and design meet the requirements of DIN 19263

• Temperature range 0 – 100°C

• Shockproof and heavy-duty (dome shaped) membranes

• pNa range < 0 to 4

• pH 2 units higher than the pNa (pH-pNa>2)

• Na+ range is 0.0001M up to saturation

Additional characteristics for type SM23-AN4

• Glass resistance @ 25°C 100-300MΩ

• Suitable (Ultra-, pure-) water application

• Shock-proof glass membrane with fast response

Additional characteristics for type SM23-AN6

• Glass resistance @ 25°C 450 - 700MΩ

• heavy-duty membrane guarantees great strength

retaining the necessary sensitivity

• Especially suitable for the more harsh processes.

For example brine applications

Note: The resistance may not exceed 1000 MΩ under measuring and calibrating conditions (according DIN the resistance of the glass may not exceed 1GΩ). As a general rule, the glass-resistance will increase by 100% with every temperature decrease of 10ºC (likewise, the glass impedance will decrease bij 50% with every temperature increase of 10ºC).
