Polarographic oxygen sensor DOG-208FA

analogppm levelfor wastewater

DOG-208FA electrode, which is specially designed to be resistant to 130 degrees steam sterilization, the pressure auto-balance high temperature dissolved oxygen electrode, for liquids or gases dissolved oxygen measurement, the electrode is most suitable for small microbial culture reactor dissolved oxygen levels on line. Can also be used for environmental monitoring, waste water treatment and aquaculture on-line measurement dissolved oxygen levels. Dissolved oxygen electrode characteristics 1.
