COD Analyzer
COD Analyzer
The COD (Chemical Oxygen Demand) is a term used to measure the quality of water. It is a measure of water pollution resulting from organic matter. This parameter is defined as the amount of oxygen (in milligrams per litre of sample) required for the oxidation of all organic matter contained in a water sample. The COD limits are set by competent authorities for various effluents permissible for accepting them in effluent treatment plants or for releasing them to the environment. Among the various methods and instruments available, a non-depressive absorption based instrument.

Easy COD Measurement
It is pre-calibrated to measure COD levels at two ranges at the touch of a key pad. No trained person is required - Outstanding Measurement Quality
COD meter employs an advanced optical system, assuring high accuracy measurements throughout the entire range - Save Space in your Laboratory
The compact size of the Meter allows the user to eliminate the clutter of bulkier and more costly equipments. - Fast Response
When a specimen is put in the cell, the COD value is indicated in digital form in about 10 seconds. - Low Cost
The amount of reagent used is as small as 2mL, which not only enables low-cost analysis, but also reduces the amount of waste liquid after measurement. - Rugged, portable design with no moving parts
- On board memory, stores up to 1000 test results along with time and date.
- Computer and printer interface
