The YSI 910 COD colorimeter is ideal for any application. This portable instrument allows you to easily take readings for COD.

A thermoreactor, such as the CR 2200, CR 3200, or CR 4200, is required to complete the COD tests.
 

The 910 colorimeter is a rugged, waterproof, single parameter instrument for the measurement of COD (chemical oxygen demand).

The EPA-approved COD test is useful for performing rapid, frequent monitoring of treatment plant efficiency, and results allow quick response to changing conditions in the waste stream while the traditional BOD5 test takes 5-days to determine results.
