There are several ways to keep an eye on the chemical oxygen demand (COD) in water with the EZ Series online analyzers. Surface water and wastewater are common uses. The COD analyzers of the EZ7000 Series are single-parameter titrators.
Method for permanganate: 

  • EZ7050, 1–20 mg/L O2
  • EZ7051, 20–200 mg/L O2.
All analyzers provide the following options: 
  1. Multiple stream analysis (1–8 streams), which lowers the cost per sampling point. 
  2. Analog and/or digital communication outputs. 
For sample preconditioning, some applications can call for the usage of an external dilution system or a sampling/filtration system. For more information on this option, visit the EZ90000 Sample Preconditioning page.
