dissolved oxygen sensors

Key Takeaways Electrochemical (polarographic/clark-type) dissolved oxygen sensors consume oxygen during measurement, creating a zero-drift error that accumulates over continuous monitoring periods Optical (luminescence quenching) sensors from ChiMay eliminate oxygen consumption, delivering zero drift over 12-month calibration intervals compared to 2–4 week maintenance cycles for electrochemical sensors In low-DO applications (< 2 mg/L), optical sensors provide…
