Chemical Oxygen Demand is a measure of the capacity of water to consume Oxygen during the decomposition of Organic matter and Oxidation of inorganic chemicals such as ammonia and nitrite.
Determinations of COD are commonly made on samples of waste waters or natural waters contaminated by domestic or industrial wastes. Dichromate Reflux method is used for the same.
Spectralab’s COD system is the one of its kind which is very fruitful in day to day COD analysis. Spectralab’s COD system follows Open Reflux method for COD analysis to give hassle free, precise and reproducible results. The COD analysis system includes COD Digester, COD Titrator, COD Vessels and Air Condensers with other accessories.
Depending upon the type of analysis, you have range of Digesters to choose from viz.
2006 D : For Digestion of 6 samples at a time.
2015 M : For Digestion of 15 Samples at a time
5015 M : For Digestion of samples having lower Cod values i.e. less than 100 ppm.
The above digestor are for Open Reflux Method
2025 D : Based on Closed reflux method for 25 samples ()
CT – 15 Titrator is the one which is dedicated only for hassle free COD titration. It is purely an automatic titrator as the dosing of the titrant and end point detection is done automatically. The results are calculated in ppm and the same can be seen either on display or the printout of the same can be taken in a tabular form by attaching a Dot Matrix printer to it. |
