Horiba DO Electrode Laboratory DO/BOD Electrode

Horiba DO Electrode Laboratory DO/BOD Electrode 9521-10D

The Horiba 9521-10D Laboratory DO/BOD Electrode delivers accurate and stable measurements of dissolved oxygen (DO) for laboratory applications, including biochemical oxygen demand (BOD) analysis. Horiba designs this electrode specifically for bench-top testing, where precision, repeatability, and long-term measurement stability are essential.

This laboratory-type electrode uses an electrochemical membrane sensing principle, which responds quickly to changes in dissolved oxygen concentration. The design supports controlled testing conditions required for DO and BOD measurements in water and wastewater analysis.

Horiba engineers the 9521-10D for routine laboratory use, allowing consistent performance during extended measurement sessions. When paired with compatible Horiba DO meters, the electrode provides reliable results that meet the needs of research laboratories, quality control facilities, and environmental testing labs.
