This electrode has Φ12, Φ19 and Φ25 types. They are specially designed to withstand 130 degrees of steam sterilization, self-pressure balance type dissolved oxygen electrode, which can be used to measure the partial pressure of dissolved oxygen in liquid or gas. This electrode is most suitable for Online detection of dissolved oxygen level in small microbial culture reactor. In addition, it can also be used for online measurement of dissolved oxygen levels in environmental monitoring, wastewater treatment and aquaculture.
