Description
BOD Meter
BOD analysis with the BODTrak™II Respirometric BOD Apparatus. Results comparable to the dilution method can be achieved in only two to three days. Use these results for process control or as a complement to the dilution method (not approved by USEPA for NPDES reporting purposes). The BODTrak II is a re-engineered version of the original Hach BODTrak. Improvements to the old system include greaseless bottle seals, a larger graphical display, improved stirring and temperature control, a smaller footprint, improved procedures with expanded options, an auto-switching power supply, and bottle fences to prevent tipping of bottles.
Benefit
Decrease total test time
The Hach BODTrak II Apparatus is easy to set up and allows for quick sample preparation for BOD (Biochemical Oxygen Demand) analysis. Simply pour a measured sample of wastewater and nutrient buffer into each of six BODTrak II bottles. Connect the bottles to the instrument’s pressure sensors, select a measurement range, and incubate. User calibration of the instrument is not necessary.
BOD results that are easy to monitor
The BODTrak II Apparatus has a large graphic display that continuously updates results. View the results at any time during the test. The instrument plots a curve of BOD over time. To review the data in detail, simply move a cursor along the curve to display results for any stored data point.
Faster than Dilution Method
Constant stirring in the bottles supplies additional oxygen to the sample and provides bacteria with greater exposure to food. This results in more rapid respiration and consumption of oxygen.
Standalone operation
The apparatus automatically ends the test and stores teh results after the chosen test length of five, seven, or ten days. This eliminates the need to be present when the test is complete.
