COD Analysis System - Manufacturer, Exporter, Supplier



COD Analysis System - Manufacturer, Exporter, Supplier

 

To keep environmental pollution levels within limit it is essential to carry out environmental monitoring regularly & perform environmental analysis by using suitable environmental monitoring systems. The effluent analysis for parameters like Acidity, Alkalinity, Ammonia, BOD, COD, Conductivity, Dissolved Oxygen, Hardness gives an idea about the effluent water quality.

 COD analysis system is one of the pollution monitoring instruments. COD analysis requires digestion of samplers using potassium dichromate and sulphuric acid. Spectralab offers three models of COD Digesters : Model 2015MCOD Digester for 20 ml sample size, Model 5015M for 50 ml sample size and 2025M for 2-5 ml sample size. The digested sample is then titrated against FeS04 , for which Model CT 15 COD Titrator is specially designed.

 

Spectralab Model 2015 M COD Digestion Apparatus is a Solid block heated unit with provision for 15 samples at a time in 40mm dia Reaction Vessels. All the samples are heated at 150°C within + 1% accuracy with utmost uniformity of temperature.

 Spectralab Model CT - 15 COD Titrator is specifically designed for titration of K2Cr2O7 against Ferrous Ammonium Sulphate. It is provided with stand for Glass Vessel along with Magnetic Stirrer & Electrode. The results can be seen on display directly in ppm. With optional printer the results can be printed in ‘Tabular Form along with date & time.

 Suitable stands and handling devices for handling & storage of reaction vessels & condensers can be supplied as accessories.


 

 SS Holder & FRP Water Tank is convenient for transferring all the 15 reaction vessel at a time from Digestion Block to cooling tank in which tap water can be circulated.

 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.

COD Digester 2006 D   :  For Digestion of 6 samples at a time.
COD Digester 2015 M  : For Digestion of 15 Samples at a time
COD Digester 5015 M  : For Digestion of samples having lower Cod values i.e. less than 100 ppm.

 The above digester 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.
