HydroTest - Chemical Oxygen Demand Index (COD) System - Brochure

The HydroTest COD System HTCOD is designed for the determination of chemical oxygen demand index (COD) using the small-scale sealed-tube method. The industry standard dichromate method can be considered as an estimate of theoretical oxygen demand. With a wide measuring range from 0 – 15,000 mg/L O2, the HTCOD is ideal for waste water testing, offering a small handheld photometer with two LED light sources housed inside a waterproof sample chamber.
