Industrial high temperature dissolved DOG-208FA


This electrode has Φ12, Φ19 and Φ25 types, which are specially designed to be resistant to 130 degree steam sterilization, self-pressure balanced dissolved oxygen electrode, which can be used for the measurement of dissolved oxygen partial pressure in liquid or gas. This electrode is most suitable for On-line detection of dissolved oxygen levels in small microbial culture reactors. It can also be used for online measurement of dissolved oxygen levels in environmental monitoring, wastewater treatment and aquaculture.
