BOD Self-check Measurement

Respiration/Biogas Determination with OxiTop® and OxiTop® Control

OxiTop® IS 6, IS 12

 

  • High-precision
  • 5-day automatic storage of measured values
  • Portable
  • Extendable
 

Complete packages for 6 or 12 simultaneous measurements
Measurement using OxiTop® is based on pressure measurement in a closed system: microorganisms in the sample consume the oxygen and form CO2; the CO2 is absorbed by NaOH, creating a vacuum that can be measured as a mg/l BOD value. The sample volume used regulates the amount of oxygen available for a complete BOD. Measurement ranges of up to 4,000 mg/l can be measured using different volumes. The OxiTop® heads (green and yellow for inflow/outflow differentiation) 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 check values or measurements over longer periods.

Measurement range 0 ... 40 digit
corresponding to
0 ... 40 / 80 / 200 / 400 / 800 / 2000 / 4000 mg/l BOD

BOD Self-check Measurement – for a larger number of samples

 

  • 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 (order no. 902 842) and the communication program Achat OC (order no. 208 990). The OC 110 controller, in combination with the OxiTop® Control S6 / S12, is ideal when other applications in addition to BOD are required.

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
 

Data sets per measurement 180 … 360 (depending on duration)
Measurement period 0.5 h … 99 days

OxiTop®- C Measuring Head

 

  • 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.
 

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.

Measuring principle Manometric with pressure sensor
Measurement of BODn
Pressure range 500 - 1350 hPa
Accuracy ±1% of value ±1 hPa
Resolution 1 hPa (corresponds to 0.7% of BODn measuring range)
