Abstract – This white paper explores how unique design features and iodide/triiodide ion pair reference chemistry help Thermo ScientificTM OrionTM ROSSTM pH electrodes deliver fast, stable and accurate measurements.

When pH measurement performance counts – A pH measurement, along with temperature and weight, is one of the three most common measurements performed in laboratories. Reliable and accurate pH measurement is critical for ensuring the quality and safety of drinking water, as well as most pharmaceutical, personal care and food products. Additionally, many industrial processes, such as chemical and petrochemical production, and wastewater treatment require constant pH monitoring to help control the process and ensure a quality product.
