BOD Self-check Measurement OxiTop® IS 6, IS 12

High-precision 5-day automatic storage of measured values Portable Extendable Complete packages for 6 or 12 simultaneous measurements Measurement using OxiTop® is based on pressure measurement in a closed system: microorganisms in the sample consume the oxygen and form CO2; the CO2 is absorbed by NaOH, creating a vacuum that can be measured as a mg/ l BOD value. The sample volume used regulates the amount of oxygen available for a complete BOD. Measurement ranges of up to 4, 000 mg/ l can be measured using different volumes. The OxiTop® heads ( green and yellow for inflow/ outflow differentiation) have an AutoTemp function: if the sample temperature is too cold, the start of measurement is automatically delayed by at least 1 hour until a constant temperature has been reached. Apart from the automatic storage of 5 measured values ( 1 value per day) , further measured values can be read at all times during or after the period of 5 days, which permits the tracking of check values or measurements over longer periods. Measurement range 0 ... 40 digit corresponding to 0 ... 40 / 80 / 200 / 400 / 800 / 2000 / 4000 mg/ l BOD
