The ProTrode pCO₂ sensor is an inline dissolved CO₂ sensor that operates on the Severinghaus principle. This dissolved carbon dioxide sensor consists of a glass pH electrode in a membrane cap filled with bicarbonate electrolyte. Carbon dioxide diffuses through the gas-permeable membrane, altering the pH value.
The membrane cap, made of titanium grade 2 (3.7025), resists corrosion. It can be replaced after 6–10 autoclaving cycles when response times are starting to increase.
The ProTrode pCO₂ sensor delivers reliable measurements for pharmaceutical and biotechnology manufacturing processes. Engineered for resilience, this dissolved CO₂ sensor is compatible with clean-in-place (CIP), sterilization-in-place (SIP), and autoclaving procedures, ensuring long-term durability.
