BOD measurement for self-monitoring OxiTop IS 6/IS 12

Complete set for 6 measurement stations, expandable to 12 with IS 12 mixing base, 230V/50/60 Hz mains power supply and 6 OxiTop® heads and other accessories. OxiTop measurements consist of pressure measurements in a closed system: the microorganisms in the sample consume oxygen and produce CO2,absorbed by NaOH, in the process. A negative pressure is created, which as a measurement value can be directly read in mg/l. The sample volume can be adjusted depending on the amount of oxygen available to make a complete BOD measurement. With varying volumes, measurements can be made in the measurement range up to 4,000 mg/l. OxiTop heads have an AutoTemp function: when the sample temperature is too cold, the measurement is automatically delayed until the temperature stabilizes, usually it takes 1 hour. In addition to the automatic memory of 5 measurement values (1 value per day), measurement values can be read manually both during and after 5 days, improving control.
