This lab-grade dissolved oxygen sensor employs a galvanic cell principle, where an oxygen-permeable membrane allows dissolved oxygen to diffuse into an electrolyte, generating a current proportional to the oxygen concentration. This signal is conditioned into a stable 0-3.0V analog output, providing a linear representation of DO levels from 0 to 20 mg/L. The sensor is designed for continuous monitoring in aqueous environments.
The probe features a robust BNC connector interface and a 2-meter cable, facilitating integration into both portable and fixed monitoring stations. With an operational pressure rating of 0-50 PSI and a typical electrode service life of one year under normal use, it is engineered for reliability in demanding field and laboratory applications, from aquaculture to environmental science.
