BOD Sensor Velp analysis system
The BOD Sensor is an exceptionally dependable instrument, designed specifically with the goal of measuring Biological Oxygen Demand (BOD) accurately, eliminating the need for mercury. This user-friendly, highly-efficient device connects directly to the sample bottle, while a built-in pressure transducer microprocessor accurately transmits the BOD value to a readily-viewable digital display and simultaneously stores the value in the sensor's memory. This storage function accommodates five measurements at 24-hour intervals, thus facilitating the analysis process throughout the week, including weekends.
Obtaining the BOD value direcly from the digital display is convenient and possible at any time, extending beyond the initial five-day period. The equipment is versatile and adaptable to diverse ranges of measurements including 90ppm, 250ppm, 600ppm, and 999 BOD. For elevated values, measurement can be achieved through a simple sample dilution procedure.
The BOD Sensor System 6 and 10 are inclusive kits designed for simultaneous analysis of 6 and 10 samples respectively. Each package includes items such as a multi-position stirring base, BOD sensors, dark glass bottles, caps for carbon dioxide absorption, and magnetic stir bars.
The stirring base is carefully designed to fulfill the user's needs, ensuring superior stirring quality for best results, while its compact design allows up to 5 bases of 6 positions (30 samples) or 3 bases of 10 positions (30 samples) to fit comfortably inside a VELP incubator (FOC 200E).
Determining BOD values is a simplified 5-step process with VELP Scientifica's innovative systems. Leveraging the respirometric technique, this system ensures consistent, accurate results in five easy-to-follow steps:
1. Insert the magnetic stir bar into the dark glass bottle, add the sample, and put the CO2 trap filled with required reagents in place
2. Initiate the incubation process
3. Attach the sensor to the setup
4. Monitor microbial activity
5. Retrieve the BOD value (ppm or mg / l), which is based on the pressure variance within the bottle due to microbial activity
