WTW OxiTop® Control 6, Control 12

WTW OxiTop® Control 6, Control 12
BOD Self-check Measurement - for a larger number of samples, with easy sample management 

• Controller-driven
• Simultaneous measurement of up to 100 samples
• Statistical evaluation
• Automatic sample ID

Complete package for 6 or 12 simultaneous measurements
OxiTop® Control system uses software-controlled functions and infrared interface to communicate with the powerful OC 100 controller. This connection enables the simultaneous, group start, management, storage and tracking of 100 measuring heads, and tracks results on a large graphic display. Data can be transferred to the PC for evaluation and documentation via the AK-540/B cable and the communication program Achat OC. The OC 110 controller, in combination with the OxiTop® Control S6 / S12, is ideal when other applications in addition to BOD are required.

Check sampling progress
The 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 a BOD value set too high for the volume used or undesired nitrification. Corrections can thus be made at an early stage.

Controller OC 100 / OC 110
Features

• Simultaneous sample management with option of grouping up to 100 OxiTop®-C measuring heads.
• Data call-up of one parallel sample with statistical evaluation and as individual data.
• Automatic calculation and graphical display of BOD value.
• Data transfer even through glass doors.
• Protocol and documentation of data via Achat OC communication program in combination with a PC.
• GLP and AQS with inspection intervals for calibration with the OxiTop® PM calibration tablets.

OxiTop®-C Measuring Head

• Instead of the usual display and keys, the OxiTop®-C measuring head has an infrared interface with which it communicates with Controller OC 100 or OC 110. By pointing the controller at an OxiTop®-C measuring head the sample can be identified and the measurement is started. Data can be called up or deleted and sampling progress can be displayed.
• Each sample is automatically assigned a unique ID number; eliminating manual sample identification even for multiple samples. In addition, statistical evaluations can be easily performed for multiple samples.
• The OxiTop®-C measuring heads have an AutoTemp function; if the sample temperature is too cold, the start of measurement is automatically delayed, by up to 4 hours, until a constant temperature can be reached. This mode can be deactivated for BOD standard.
• The measuring heads can store up to 360 data sets. Data are automatically stored in the corresponding interval according to the interval period set (0.5 h to 99 days).
• The built-in pressure sensor can register differences in pressure ranging from 500 to 1,350 hPa.
