Thermo Fisher, 210058, Accessories and Kits for Orion™ 2111LL Low Level Sodium Analyzers

Orion™ 2111LL Half-Cell Reference Electrode is used as the reference half-cell in the Orion 2111LL Low Level Sodium Analyzer. The electrode provides the stable reference potential required for accurate potentiometric sodium measurement when paired with the corresponding sodium-sensing half-cell. This replacement component is intended specifically for the 2111LL analyzer system and is useful during preventive maintenance, electrode replacement, or troubleshooting when reference performance has degraded. The specified ambient operating temperature range is 5–45°C. Using the matched reference electrode helps preserve analyzer response and measurement stability in low-level sodium monitoring applications such as high-purity water and process-water control. The component can also be purchased as part of the 2111LL electrode kit together with the sodium half-cell and reference-electrode filling solution.
