Process colourimeter for chemical oxygen demand

Applikon Analytical has introduced the ADI 2019 D process colourimeter for chemical oxygen demand (COD) which carries out thermal digestion without contact with the colourimetric measuring cell.

After the launch of the ADI 2019 D process colourimeter from Applikon Analytical comes the first 'off the shelf' version for Chemical Oxygen Demand (COD).

The digester/cuvette module allows the analyser to carry out the thermal digestion for the prescribed period without contact with the colourimetric measuring cell.

Upon completion of the digestion period the initial colour of the digested sample is measured to prevent background sample colour interfering with the accuracy of the analysis.

After the addition of dichromate solution a second colour measurement is made to provide the true Chemical Oxygen Demand value.

Two models of the ADI 2019 D for Chemical Oxygen Demand are available.

The lower range model provides analysis in the range 0 - 5,000 mg/l and the higher range extends the analysis from 0 - 20,000 mg/l.

Both models feature automatic cleaning, automatic validation of out of range results and automatic calibration as standard.

Housed in an IP65 enclosure the analyser is suitable for mounting in process areas without further protection and a full range of accessories such as self-cleaning filters are supplied.
