How electrode design correlates with optimum performance in pH measurement

18 Apr 2022

In this application note, Thermo Fisher Scientific discusses how the design features and iodide/triiodide ion pair reference chemistry help Thermo Scientific™ Orion™ ROSS™ pH electrodes deliver fast, stable, and accurate measurements.

Thermo Scientific™ Orion™ ROSS™ Combination pH Electrode

Thermo Fisher Scientific

Get results three to five times more precise than those obtained with conventional electrodes with the Thermo Scientific™ Orion™ ROSS™ Combination pH Electrode. Built to provide stable readings to 0.01 pH in less than 30 seconds. The epoxy body makes this durable electrode ideal for rugged environments. The electrode is accurate even in extreme cases of samples varying from one to another by 50°C or more. Drift is less than 0.002 pH per day, restandardization is minimized.
