Bod measurement system bd 600accurate, Automatic and direct control of your wastewater samples highlights user friendly large brilliant graphic display graphical representation of measured values usb & sd card interface mercury, Free, Environmentally, Friendly remote control user, Selectable time span from 1 to 28 days free individual programming of each of the six samples inductive stirring system, 110 operating at 240 volts / 5-0, 6-0 hz biochemical oxygen demand bod bod biochemical oxygen demand is an expression for the quantity of oxygen required for biological degradation of organic matter in a waste water sample. Bod measurement is therefore employed as a basis to recognize of biologically degradable organic matter in water. The difference between bod and chemical oxygen demand cod is that cod additionally registers biologically non, Degradable organic matter. Bod measurement is therefore an important assessment of the effects of domestic and industrial waste water on sewage plants and outflow respirometric bod, Points. Manometric measurement using the lovibond bd 600 the lovibond sensor system bd 600 is a 6 sample system that allows precise measurements of bod founded on the manometric principle. Manometric respirometers relate oxygen uptake to the change in pressure caused by oxygen consumption while maintaining a constant volume. Due to the modern integral pressure sensors, It is no longer necessary to use mercury for pressure measurements. Bd 600 principlerespirometric methods provide direct measurements of the oxygen consumed by microorganisms from an air or oxygen, Enriched environment in a closed vessel under conditions of constant temperature and agitation. Carbon dioxide produced metabolically by the bacteria is chemically bound by the potassium hydroxide solution housed in the seal cup in the bottle. The outcome is a pressure drop in the system, Which is directly in relation to the bod value and is quantified by the bod sensor. The bod level is then displayed directly in mg/l. The bod values are stored automatically in the sensor memory in regulary intervals and may function as called up on the large, Format display at your convenience without the requirement for time, Consuming conversion using factors. This means that test series that end on a sunday can be evaluated during the following week without any problem. Measurement series can be stored on usb stick/sd card or transferred via usb cable to evaluate the datas on a computer. The measurement period is user, Selectable between 1 and 28 days to match the application. While short measurement periods are useful for standard bod, Scientific applications measurements typically extend over a period of 5 days and generally takes manometric determination, Place over, For example of oecd a period of 28 days. Evaluation of measurementsthe bd 600 measuring system records a measurement once every hour, Independent of the length of the measuring period. This way the caliber of the series of measurement can be evaluated in an early stage. Current values and stored values may be called up at any time. Stored value can be displayed numerically or graphically. The table/ graph on the left illustrates an example of bod5 evaluation. The development of bod over a period of five days is easily seen.
