The interpretation of the pressure differences in the temporal course depends 
on the measured material and its preparation and on the sample manipulation 
(e. g. intermediate aerations) during the measuring period.

1.3

Data management

The measuring head records the measured values and stores the measuring 
data. Using the controller, the collected and stored data are read out from the 
measuring head and stored in the “sample management“. Starting at the 
OxiTop

®

 sample management, it is possible to make the graphical and statis-

tical evaluation of the sample data. 

The data can be transferred from the controller to a computer via the RS232 
interface. The read-out software Achat OC facilitates to process the stored data 
further. 

Additionally, the data can be transferred to an IR printer via the IR interface.
