Description
Measure sodium in aqueous solutions quickly, accurately and economically with Thermo Scientific™ Orion™ Sodium Electrodes. A unique redox internal system with a Thermo Scientific™ Orion™ ROSS™ electrode provides faster response, and greater stability and accuracy than conventional sodium electrodes.
The sodium electrode is commonly used to measure samples such as food, beverages and animal feed.
Features:
- 8611BNWP is a combination electrode with a Sure-Flow™ junction that allows easy cleaning. When conventional electrode junctions clog, the Sure-Flow junction can be opened and flushed clean simply by pressing the cap. 8411BN is a half cell sensor that requires ROSS reference electrode, Cat. No. 800300 or the ROSS Ultra reference electrode, Cat. No. 800500U to function.
