Reagent COD is test equipment for chemical oxygen demand. Determination of high range Chemical Oxygen Demand (COD) by the Reactor Digestion method. US EPA approved for wastewater analysis using Hach Method 8000. Range: 20 -1500 mg/L COD. Pack of 25 vials. Reagent COD consists of 3 elements, namely:

• EPA Approved

Low Range (LR) and High Range (HR) vials are approved by the USEPA for NPDES reporting of wastewater COD concentrations.

• Simpler and Safer

Prepared COD reagents eliminate the need measurement of corrosive and toxic chemicals. Just add sample to the COD vial, digest and measure. Photometric measurements provide accurate results without the equipment and effort required for titrations.

• Easy Disposal

Small reagent volumes used in Hach COD vials minimize the volume of spent silver, mercury and chromium waste. Customers in the contiguous 48 United States benefit from the availability of the COD waste recycling program, which provides comprehensive transportation and disposal of COD vials.
