COD Digestors Chemical Oxygen Demand
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.
How to use –
Get the machine cleaned with soft cloth before art of the work.
Now insert the plug in the main, switch on and mains pilot lamp glow.
Set the temperature on 1Way Heat Switch for providing heat fast and slow to the partials as your convenient.
Set the temperature on PID digital control.
If desired, use arrow keysto change SV.
the temp. UP and down and Press set button
The manual of PID is enclosed with this manual but you shouldn’t try to pre set the program for maintaining accuracy of temperature.
The PID controlled the temperature before 15 to 20 as the set temperature and temperature will be increase slowly and maintain it on highest point as your requirement
