M4 Knick SE740 — Low-Maintenance Optical Oxygen Sensor

The SE740 uses optical sensing for dissolved-oxygen measurement in industrial and hygienic processes. Its polished stainless steel construction supports applications requiring cleanable surfaces, while its measurement principle avoids dependence on process flow.

Maintenance involves replacing the sensing cap without electrolyte replacement or polarization. The sensor supports sterilization, autoclaving, and clean-in-place procedures.
