The compact, reliable, cloud-enabled solution for BOD determination and aerobic respirometric tests.

The VELP RESPIROMETRIC Sensor BOD is designed to provide a smart and cloud-enabled solution to laboratories of water and wastewater quality control.

BOD (Biochemical Oxygen Demand) Determination is a simple and easy way for monitoring the microorganisms’ activity in water samples with extremely reliable results.

In particular, microorganisms present or inoculated in a water sample containing biodegradable organic substance, consume oxygen for their metabolic activity and produce a corresponding volume of carbon dioxide.

The carbon dioxide gets absorbed by a strong alkali positioned in the neck of the bottle. The result of this process is a decrease in gas pressure. The BOD measures this change in gas pressure between the beginning to the end of the analysis and gives a result expressed in mg/l.

• The bright 4-digit LED display ensures long battery life in respect of other sensors in the market
• Intuitive 2 button interface to facilitate the analysis set up
• Pressure range: 500 ÷ 2000 mbar (hPa)
• Results available in BOD (mg/l) and Pressure (mbar)
• BOD Scales: 90, 250, 600, 1000, 4000, Higher values after dilution
• Automatic pressure results conversion in BOD

The RESPIROMETRIC Sensor transmits data directly to the PC enabling real-time monitoring of the analysis curve. Respirometric studies can last days and even months, the unique VELP solution ensures constant monitoring of multiple analysis from an intuitive proprietary software, the RESPIROSoft.

The VELP DataBox is included in the Systems together with the RESPIROSoft Software and enables wireless data transmission from the RESPIROMETRIC Sensor to the PC.

The DataBox stores result for up to 48 RESPIROMETRIC Sensors (8 systems).
