I. Overview
SYB-3 BOD AutomaticAnalyzeristheuseoftheairpressuredifferencemethodforanewtypeinstrumentfordeterminingbiochemicaloxygendemand. Duetotheuseofsingle-chipmicrocomputermeasurementtechniquesandadvancedsensing,chemicaldilutionmethodsandinstrumentscanprovidecomparableresults,andeight-channel BOD measurement(mg/l)direct-reading,real-timedataandbiochemicalresponsecurvesforprinting,easytouseandmaintain,andotheradvantages.

II . Workingprinciple
Biochemicaloxygendemand( BOD ) , Isundercertainconditions,throughreproductionofaerobicmicro-organismsinthewaterandbreathedissolvedoxygenconsumedbydecompositionoforganicsubstancesinwater. Water BOD valuesaregenerallysample 20℃place 5daystheamountofdissolvedoxygenconsumed(mg/l), creditedas BOD 。
Duringthemeasuringprocess,dependingonthemeasuringrangeselectionmeasuringrange,willsettheamountofvolumeofwaterpouredintotheflask,addtemperaturecontrol 20℃±1℃incubator,after 5 daysoftraining,throughbio-oxidationoforganicmatterinsamples,convertedintonitrogen,carbonandsulphuroxides. Inthisprocess,ranonlyonegascarbondioxidefromthewatersampleswerepreviouslyplacedinabottleofsodiumhydroxide(orpotassiumhydroxide)absorption. Therefore,reducetheairpressureinthebottleandisproportionaltotheamountofdissolvedoxygenconsumedbymicroorganisms,bymeasuringpressurechangestoget BOD values.
