Test Apparatus

APPLICATION:

The chemical oxygen demand (COD) is a measure of water and wastewater quality. The COD test is often used to monitor water treatment plant efficiency. This test is based on the fact that a strong oxidizing agent, under acidic conditions, can fully oxidize almost any organic compound to carbon dioxide. The digester will be used for potassium dichromate - sulphuric acid digestion of water/waste water samples.   FEATURES:

·  Designed for Chemical Oxygen Demand method for monitoring wastewater influent and effluent, industrial process water in Pollution control Labs. 

·  Double walled construction. Complete Equipment made from CRCA Steel, Duly powder coat finished.

·  Highly insulated with compressed Cerawool between the walls to minimize the heat dissipation

·  Aluminum Block having holes used to hold Glass tubes is heated to maintain temperature up to 180˚C.

·  Dual Display Microprocessor based PID Temp. Controller cum Timer with PT-100 sensor.

·  Timer facility with alarm to set the Digestion period (Refluxing).

·  Timer Range: 999 Minutes.

·  Temperature Range: 5˚C above ambient to 200˚C

·  Accuracy                     : ± 1.0˚C.

·  Block Hole Dimension: 40mm Dia X 80 mm Depth.

·  Glass Tube Size: 38 mm Dia.

·  Air Condenser: 600 mm Height.
