MB-DBO´s software interface

The MB-DBO software, developed by BIOSENSORES, represents accurately and in real time: The values of BOD and Dissolved Oxygen (DO) in a temporal graph. The sequence of the process being carried out by the device. The latest BOD data collected in the previous analysis. The remaining time for the start of each process. The remaining time until the end of the analytical cycle. An alarm box that shows possible failures: "connection failure between the computer and the microprocessor” or “the sample has exceeded previously preset"
