Inline pCO2 Sensors

Ideal for biotechnological and pharma applications, this inline dissolved CO2 probe is able to measure from 10 mbar up to 800 mbar (approximately 0.145 – 11.6 psi) pCO2. The design and materials used in its production ensure low maintenance and reliable performance over its lifetime.

The probe shaft is made of stainless steel (316S) with an exchangeable silicone membrane. The dissolved carbon dioxide probe can be used in hygienic environments; compliance with cGMP and FDA regulations is fulfilled as this sensor is designed for CIP, SIP, and autoclave conditions.
