Orion™ Sodium Electrodes
Catalog number: 8611BNWP
Have Questions? 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.
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 either ROSS reference electrode 800300 or ROSS Ultra reference electrode 800500U to function.
