BOD Sensor BOD Analysis Innovative, mercury-free and extremely reliable solution for BOD analysis (Biochemical Oxygen Demand). BOD Sensor is the innovative, mercury-free and extremely reliable solution for BOD analysis. A microprocessor-controlled pressure transducer transfers the Biochemical Oxygen Demand value directly to the display: results are displayed directly in mg/l with no need for further calculation and are stored automatically in the BOD Sensor. The process is extremely easy, based on just few simple steps : 1. Add a stirring bar, fill the bottle with the sample and insert CO2 trap, filled with reagents 2. Incubate 3. Screw the sensor 4. Monitor the microorganism activity 5. Read the BOD value (ppm or mg/l), based on the pressure change into the bottle because of microorganisms’ activity Precise Control - Measurement on scales of 90, 250, 600 and 999 ppm BOD - Higher values can be measured by diluting the sample - Models with stirring stations offer VELP stirring quality Extremely Practical - Fits directly on the bottle containing the sample - Automatically stores 5 BOD values at 24-hour intervals - Enables analysis to continue over the weekend - Results directly readable at any time, even after five days - Direct readout in mg/l (ppm) - Compact stirring stations Priority to Safety - IP 54 protection against particle and liquid ingress - Class 3 IEC 1010 conformity Choice of Models - BOD Sensor Set, a ready-to-use solution for individual BOD analysis only; BOD Sensor, a dark glass bottle, an alkali holder and a stirring bar.; BOD Sensor Set is designed for use with the VELP MST stirrer. - BOD Sensor System 6, a complete package for 6 tests : 6-position stirring station, 6 BOD Sensors, dark glass bottles, alkali holders amp; stirring bars. - BOD Sensor System 10, a complete package for 10 tests : 10-position stirring station, 10 BOD Sensors, dark glass bottles, alkali holders amp; stirring bars.
