The EZ Series Online Analysers offer multiple options to monitor Chemical Oxygen Demand (COD) in water. Typical applications are wastewater and surface water.
The EZ7000 Series COD Analysers are single-parameter titrators.
Permanganate method:
- EZ7050, 1 - 20 mg/L O₂
- EZ7051, 20 - 200 mg/L O₂
Options for all analysers include:
- Multiple stream analysis (1-8 streams) reducing cost per sampling point
- Analogue and/or digital outputs for communication
Some applications may require the use of a sampling/filtration or an external dilution system for sample preconditioning. For this option please check the EZ9000 Sample Preconditioning page.
