DOG-208FA High Temperature fermentation

Dissolved Oxygen Electrode

DOG-208FA DO electrode, which is specially designed to be resistant to 130 degrees steam sterilization, the pressure auto-balance oxygen electrode, for liquids or gases dissolved oxygen measurement, the electrode is most suitable for small microbial culture reactor dissolved oxygen levels on line. Also can be used for environmental monitoring, wastewater treatment and aquaculture in-line measurement of dissolved oxygen levels. Size Φ12, Φ19 and Φ25 type for option.
