ProTrode pH sensors: Sistem

The ProTrode 200 sensor is a combined pH sensor with integrated Pt1000 designed to perform inline pH measurements biotechnology and pharmaceutical processes. This non-pressurized sensor has a measuring range from 0 – 12 pH and because of its unique sleeve diaphragm design, enables very accurate pH measurements with low response time’s independent of the process flow.The included Ag guard prevents silver fouling into the process and diaphragm blockage in processes containing sulfide or proteins. 

The ProTrode 300 sensor is a combined pH sensor with integrated Pt1000 designed to perform inline pH measurements in biotechnology and pharmaceutical processes. The pressurized sensor has a measuring range from 0 – 12 and ceramic pin diaphragm design, which enables accurate pH measurements, with good response times.The included Ag scavenger prevents silver fouling into the process and diaphragm blockage in processes containing sulfide or proteins. 

The ProTrode 250 sensor is a combined pH sensor with integrated Pt1000 designed to perform inline pH measurements in chemical processes which require demanding sensor specifications. The pressurized inline pH sensor has a measuring range from 0 – 14 pH and a unique sleeve diaphragm design, which enables very accurate pH measurement, with low response time’s independent of process flow.

The ProTrode 350 sensor is a combined pH sensor with integrated Pt1000 designed to perform inline pH measurements in chemical processes which require demanding sensor specifications. The pressurized inline pH sensor has a measuring range from 0 – 14 pH and a ceramic pin diaphragm design, which enables very accurate pH measurement, with low response time’s independent of process flow.

The ProTrode 400 sensor is a combined pH sensor with an integrated Pt1000, designed for inline pH measurements in chemical processes. This non-pressurized sensor offers a measuring range from 0 to 14 pH. Its perforated diaphragm design aims to reduce the risk of clogging. This supports performance in media with high particle content, such as slurries. The ProTrode 400 uses high alkaline H glass for accurate measurements at higher pH values.

The ProTrode dissolved oxygen (DO) sensor is an advanced optical dissolved oxygen (ODO) sensor that delivers accurate, real-time measurements utilizing state-of-the-art optical technology. Its durable construction enables compatibility with CIP (Clean-In-Place), SIP (Sterilize-In-Place), and autoclaving processes, making it well-suited for rigorous bioprocess environments. Continuous dissolved oxygen monitoring enables precise control of oxygen levels, thereby reducing variability, enhancing batch consistency, and supporting regulatory compliance while minimizing both downtime and maintenance requirements. The ProTrode DO is a low-maintenance inline dissolved oxygen sensor that delivers reliable measurements from 0 to 250% air saturation. Built to high hygienic standards, it is able to withstand CIP and SIP processes. Its PTFE-reinforced silicone membrane is easily replaceable, ensuring stable performance and minimal downtime.

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.
