Product name:
Analog pH Sensor
Product series:

CPS41

Product brand:
E+H/Endress+Hauser
Product feature:
• ATEX, FM and CSA certified for use in hazardous explosive areas • Continuous KCl electrolyte replenishment together with separate reference lead provides anti‑poisoning performance for the electrode • Uses KCl electrolyte to measure media with extremely low conductivity (≥ 0.1 µS/cm) • Suitable for CIP and SIP cleaning • Ideal for measuring applications with rapidly changing media: the combination of liquid KCl electrolyte and ceramic diaphragm shortens response time

Measuring principle:
pH is the unit for measuring the acidity and alkalinity of a medium. An electrochemical potential develops on the glass membrane of the electrode, and its magnitude depends on the pH value of the medium. Hydrogen ions (H⁺) accumulate selectively on the outer membrane, generating an electrochemical potential — an electrochemical boundary layer with a potential difference. The built‑in Ag/AgCl reference system serves as the reference electrode. The measured voltage is converted into the corresponding pH value based on the Nernst equation.

Standard
Using scenario:
Ceraliquid CPS41 is a high‑performance analog electrode for measuring media under harsh conditions in the chemical industry, including low‑conductivity media and media with high concentrations of organic solvents. Its fast response ensures high process safety even in applications with rapidly changing medium composition. Suitable for low‑conductivity media, high‑concentration organic solvents or alcohols, and measuring points with rapidly changing media: chemical industry, power plants (e.g. boiler feedwater), and life‑science applications such as water for injection.
