COD Sensors (Chemical Oxygen Demand) provide instantaneous data on organic pollutants using UV-VIS absorption. This reagent-free method enables 24/7 effluent monitoring, eliminating laboratory delays for immediate process control and environmental safety.
Our sensors provide the rapid feedback required for automated industrial automation and strict regulatory compliance in any ETP or STP environment.
Reagent-Free Analysis: Eliminate expensive and hazardous chemical reagents used in traditional laboratory methods.
Benefit from rapid local support, including calibration verification and on-site technical consultation.
Integrated sensors correct for turbidity to ensure COD readings are unaffected by water "cloudiness."
Provide the 24/7 data flow required by regulatory bodies (like CPCB) for continuous monitoring.
Nuicon utilizes “reagent-free” optical technology to provide a sustainable and cost-effective alternative to chemical-based COD analysis.
Choosing an optical sensing principle eliminates the need for hazardous chemicals and minimizes the total cost of ownership.
Ideal For:
Industrial wastewater, municipal sewage, and environmental river monitoring.
Features:
UV 254nm absorption technology, automatic turbidity compensation, and non-contact measurement.
Explore Analyzers

It measures UV light absorption at 254nm; organic pollutants absorb this light, allowing the sensor to calculate COD concentration.
It offers high correlation ($R^2 > 0.9$) and is superior for detecting rapid spikes in real-time, unlike manual sampling.
Minimal maintenance involves checking the wiper and cleaning the optical windows every 1–3 months.
Yes, our TOC COD BOD TU Controller estimates BOD and TOC based on the UV absorption data.
Yes, we provide traceable NABL Calibration certificates from our Bangalore center to ensure your facility is audit-ready.
