|Complete packages for 6 or 12 measuring stations|
|Measuring with OxiTop® based on a measurement of the pressure in a closed system. The microorganisms that are found in the sample consume CO2 in forming oxygen. Thereof is absorbed with NaOH. It follows a depression which the measurement can be read directly in the BOD in mg / l.
Depending on the volume of sample used, oxygen is available rule to perform a complete BOD. Using different volumes can be measured measuring ranges up to 4,000 mg / l.
The OxiTop® heads (green and yellow to distinguish the input from the output of a processing unit) have an AutoTemp function: if the sample temperature is too cold, the start of measurement is automatically delayed until it reached a constant temperature (at least one hour).
In addition to automatic 5 measurement values recording (day 1 value), it can be read at any time other values in the meantime or at the end of five days, which may follow control values or measurements over long periods.
