OxyFerm FDA MS Details

OxyFerm FDA Memosens is an electrochemical polarographic dissolved oxygen (DO) sensor specifically designed for applications with high demands for hygiene in the pharmaceutical, biotechnology, and food & beverage industries. Building on Hamilton's proven electrochemical DO sensor technology, OxyFerm FDA provides reliable dissolved oxygen measurements across a wide measuring range while meeting the requirements of hygienic production processes.

The sensor is equipped with a specially designed FDA-approved membrane with a rounded geometry that helps prevent gas bubble accumulation and ensures reliable measurement performance in sterile process environments. Its robust construction withstands steam sterilization, autoclaving, and CIP cleaning, supporting long-term operation under demanding hygienic process conditions.

The OxyFerm FDA Memosens offers increased installation flexibility through a wide range of electrical connectors, process mounting options, and optional accessories. The traditional nanoamp (nA) output enables compatibility with a broad range of commercially available transmitters and process control systems.

Combining hygienic design, robust construction, and reliable electrochemical measurement technology, OxyFerm FDA provides a dependable solution for dissolved oxygen monitoring in sterile and hygienic process applications.

  • We particularly appreciated the professional and personable approach.

    The training on pH sensors was highly beneficial for us. After a detailed introduction to the fundamentals of pH measurement, electrode measurement principles, and the topic of troubleshooting/prevention, we had sufficient time to ask our specific questions. This enabled us to apply what we learned immediately and integrate it directly into our laboratory routine. We particularly appreciated the professional and personable approach of Mrs. Näf-Rüdiger, who guided us through the informative and application-oriented training session.

FAQ

Does salinity impact my DO measurement?

Yes, salinity of a solution generally has an inverse relationship to the dissolved oxygen content within the solution. Arc sensors can have the salinity value of the liquid added in to correct the measurement by using ArcAir.

FAQ

How much torque is needed to install a sensor with PG13.5 threads?

Sensors with PG13.5 threads rely on the o-ring to seal against process pressure. Finger-tight (approximately 2 Newton Meter or 18 inch-lb) should be sufficient to install the sensor without leakage. Additional tightening beyond this can deform the o-ring or strip the threads.
