the evidence backs this
Recorded sources
4 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that sensors can measure BOD and COD in real time?

Yes. Sensors and soft-sensing techniques are capable of measuring Chemical Oxygen Demand (COD) in real time for wastewater monitoring.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked

The analysis

Multiple retrieved sources demonstrate the real-time measurement or estimation of Chemical Oxygen Demand (COD) using direct online sensors, microbial fuel cell biosensors, or soft sensors. No papers refute the claim.
