The ProTrode pCO? sensor is an inline dissolved CO? 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 pCO? sensor delivers reliable measurements for pharmaceutical and biotechnology manufacturing processes. Engineered for resilience, this dissolved CO? sensor is compatible with clean-in-place (CIP), sterilization-in-place (SIP), and autoclaving procedures, ensuring long-term durability.
