B.O.D Determination Systems (mercury-free)
Biological Oxygen Demand / Biochemical Oxygen
Demand (B.O.D.) is an index of the degree of organic pollution in water. It is
the amount of oxygen by a unit volume of water at a given temperature and for a
given time.
The Velp system uses the innovative ecological BOD sensor (without mercury) which is equipped with advanced microelectronics. A microprocessor controlled pressure transducer allows a direct reading of measurement by way of the display. Data can be collected for 5 days and can be read for 21-28 days. The sensor is powered by long lasting (2 years) lithium batteries and is free from any electrical connection
Features and benefits:
- Direct reading of values in mg./l. (without factor)
- BOD measurement without mercury filled manometers
- Easy, precise and immediate reading values by a display, preventing posible errors in data transcription
- Operation without any needs of controls
- Memorised storage of 5 BOD measurements at 1 day intervals
- Possibility of continued incubation up to 21-28 days (BOD last)
- 4 measurement scales (90, 250, 600, 999 mg/l) and higher values after sample dilution
- Alarm for values out of scale
