Monitoring water quality is essential for environmental laboratories, wastewater treatment plants, and industries that discharge effluents. One of the most important parameters in water testing is COD – Chemical Oxygen Demand. To perform COD testing with accuracy, laboratories rely on a precise and reliable COD Digester Apparatus.
Hema Scientific Instruments, a leading manufacturer of laboratory and environmental testing equipment, offers a high-performance COD Digester engineered for accuracy, durability, and compliance with standard testing methods.
A COD Digestion Apparatus is a laboratory device used to measure the chemical oxygen demand in water by heating samples with COD reagent at a constant temperature. It ensures precise digestion of water samples to analyze the amount of organic contaminants. COD testing is a critical part of environmental monitoring, effluent analysis, and water quality control.
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
