Oxitop IS 6, IS 12
Measurement using Oxitop is based on pressure measurement in a closed system: microorganism in the sample consume the oxygen and form CO2. This is absorbed by NaOH, creating a vacuum which can be read directly as a measured value in mg/ L BOD.
The used sample volume regulates the amount of oxygen available for a complete VOD. Measurement ranges of up to 4000 mg/ L can be measured using different volumes.
The Oxitop heads ( green and yellow for differentiation of inflow/ outflow) 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 checks values or measurements over longer period.
Measuring principle : Manometric with pressure sensor
BOD range : 0-4000 mg/ L
