The most convenient way to get reliable results automatically for BOD analysis. Data management and reporting become incredibly intuitive with the wireless data transmission to the exclusive BODSoft™.


Remote Operation

  • Unique and revolutionary wireless sensor transmits data
  • Wireless DataBox™ records transmitted data
  • Dedicated BODSoft™ software processes the data
  • Up to 80 sensors can be monitored simultaneously


Precise Control

  • Measurement on scales of 90, 250, 600 and 999 ppm BOD
  • Higher values can be measured by diluting the sample

BOD Analysis has never been so easy!

BOD Sensor is the innovative, mercury-free and extremely reliable solution for BOD analysis. A microprocessor-controlled pressure transducer transfers the Biochemical Oxygen Demand value directly to the display: results are displayed directly in mg/l with no need for further calculation and are stored automatically in the BOD Sensor.


The process is extremely easy, based on just few simple steps: 1. Add a stirring bar, fill the bottle with the sample and insert CO2 trap, filled with reagents
2. Incubate
3. Screw the sensor
4. Monitor the microorganism activity
5. Read the BOD value (ppm or mg/l), based on the pressure change into the bottle because of microorganisms’ activity


Exclusive Performance, Wireless Technology
Thanks to the innovative wireless technology, the sensor transmits the BOD value (directly in ppm or mg/L) to the Wireless Databox™, based on the data transmission frequency set before starting the analysis.
Results are then displayed from the intuitive BODSoft™, the optimal solution for data management and comparison of the results.
