Description
COD Digestors Chemical Oxygen Demand
The conventional Hot Plate Method has a number of disadvantages. The COD digester overcomes these disadvantages. This digester has a uniform heating without water circulation. The Switch auto off system is its unique feature. After completion of labpro digestion, titration can be done manually or by COD autotitrator
Outer cabinet made of mild steel duly Coated. Double wall construction with insulation for minimum heat losses increases the efficiency of the system. Aluminium Block with holes is used to hold 15 nos .COD tubes.( or For 6 tubes ) Aluminium Block is heated to maintain temperature up to 180 °C . Solid state Digital Temperature Controller, labpro appropriate heater & insulation selection assure uniformity in all the samples.
