VELP - Biochemical Oxygen Demand Analysis Sensor

Precise Control

• 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

Extremely Practical

• 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

Choice of Models

• BOD Sensor Set, a ready-to-use solution for individual BOD analysis only
  BOD Sensor, a dark glass bottle, an alkali holder and a stirring bar.
  BOD Sensor Set is designed for use with the VELP MST stirrer.
• BOD Sensor System 6, a complete package for 6 tests
  6-position stirring station, 6 BOD Sensors, dark glass bottles, alkali holders & stirring bars.
• BOD Sensor System 10, a complete package for 10 tests
  10-position stirring station, 10 BOD Sensors, dark glass bottles, alkali holders & stirring bars.

Stirring stations are designed for simple handling, ensuring the VELP stirring quality.
Up to 5 stirring stations with 6 positions (30 samples) or 3 stirring stations with 10 positions
(30 samples) can be placed in a VELP incubator (FOC 215E)

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
