BOD – Biochemical oxygen demand is one of the important parameter of effluent analysis. The SPECTRALAB Microcontroller based BOD Monitor system is based on well known principle of “ Electrolytic Respirometry” In this method exact quantity of oxygen is supplied as per demand & the oxygen required can be directly noted in mg/liter against time.
BOD Monitor is designed to measure the oxygen uptake of a given sample continuously. It consist of Cell assembly, Electronic Unit & Magnetic Stirrer. The Sample is kept in continuous stirring to ensure constant absorption of OXYGEN.
BOD is to be reported at 27°C for 3 days. However, with this instrument after studying routine samples the BOD can be predicted with in 1 ½ to 2 days by using prediction factor.
