Spectralab Instruments Pvt. Ltd.

The Environmental Monitoring of BOD Monitors we offer are designed for perfection. BOD stands for Biochemical Oxygen Demand, which is an important parameter for effluent analysis. To overcome all the disadvantages of this process, we have come up with new Microcontroller Based BOD Monitors (Model EM2) that is capable of providing more information conveniently. These new BOD monitors can give full record of Oxygen Uptake Rate with Graphical Representation.

 

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

2015 M is solid block heated unit that can provide 15 samples at one go in 39mm dia Reaction Vessels. The samples are heated at 150°C within + 1% accuracy maintaining utmost uniformity of temp.

Some of the salient features are as follows :

• Compact in Construction

• No Water Circulation

• Standard APHA Method

Glassware Handling Kit

Product Code:

COD-2015M

The Environmental Monitoring system (COD 2025D) we offer is widely appreciated for its exclusive features such as compact design, uniform temperature and accurate result. These are ideal for COD digestion and other similar digestions and can accommodate 25 closed cap vials of 16mm diameter.

 

The salient features of this system are as follows:

 

• Digital timer turns off power automatically after elapsed time
