Automated BOD, CBOD, and DO Analyzers

The EasyPREP BOD-200 and EasyPREP BOD-300 provide users with the capability to conduct dissolved oxygen DO measurement for the calculation of BOD and CBOD analysis. Analyze CBOD in conjunction with BOD to verify if non-compliant BOD results are due to nitrification and to obtain results more reflective of real effluent quality when under nitrifying conditions.


The BOD-200 and BOD-300 may be operated with an Optical or a Membrane Probe. The Optical Probe requires no membrane maintenance or electrolyte re-filling, and it is characterized by its stable response and minimal drift. The BOD-300 automates capping and decapping of BOD bottles.
