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:
Add a stirring bar, fill the bottle with the sample and insert CO2 trap, filled with reagents
Screw the sensor
Monitor the microorganism activity
Read the BOD value (ppm or mg/l), based on the pressure change into the bottle because of microorganisms’ activity
Measurement on scales of 90, 250, 600 and 999 ppm BOD
Higher values can be measured by diluting the sample
Models with stirring stations offer VELP stirring quality
Fits directly on the bottle containing the sample
Automatically stores 5 BOD values at 24-hour intervals
Enables analysis to continue over the weekend
Results directly readable at any time, even after five days
Direct readout in mg/l (ppm)
Compact stirring stations
Priority to Safety
IP 54 protection against particle and liquid ingress
Class 3 IEC 1010 conformity
