A COD Digester, also known as a Chemical Oxygen Demand Digestion Apparatus, is a heating block designed to digest water or wastewater samples at 150°C for 2 hours as per the APHA, BIS, and EPA standards.
It provides uniform heating for multiple samples simultaneously, ensuring complete digestion before titration or spectrophotometric analysis.
This equipment is widely used in:
-
Environmental testing laboratories
-
Industrial effluent treatment plants
-
Sewage treatment plants (STPs)
-
Water testing facilities
-
Research institutes
-
Pollution control boards
