OxiTop® Control

OxiTop® Control Biological Oxygen Demand (BOD) Instrumentation is an advanced version of the successful OxiTop® BOD Instrumentation system that uses software-controlled functions and an infra-red interface to communicate with a handy controller, the OC 100. This BOD instrumentation system enables the simultaneous and grouped start, management, storage and tracking of 100 BOD measuring heads via the controller and allows them to be tracked on a large display with graphic evaluation. BOD measurement data can be transferred to the PC for evaluation and documentation via the AK-540/B cable (order no. 902842) and the communication program Achat OC (order no. 208990).

The Biological Oxygen Demand (BOD) data can be called up at any time, even during sampling, thus enabling checking of the samples for errors. The display of the progress curve allows immediate detection of irregularities and interferences, such as having the BOD value set too high for the volume used or undesired nitrification. BOD measurement corrections can thus be made at an early stage. OxiTop® Control BOD instrumentation offers you simple operation, improved controllability, non-toxicity, and measuring ranges of up to 4,000 mg/l BOD.

• Non-Toxic
• Stores 100 user-defined routine measurements
