BODTrak II Respirometric BOD Apparatus Range 0 - 700 Mg/L In Municipal Wastewater

Simplify 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.

• 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.
• Constant stirring in the bottles supplies additional oxygen to the sample and provides bacteria with greater exposure to food.
• The BODTrak II Apparatus has a large graphic display that continuously updates results.
• The apparatus automatically ends the test and stores teh results after the chosen test length of five, seven, or ten days.
• The BODTrak II Apparatus measures BOD using the respirometric method. Each sample bottle is connected to a pressure sensor in a closed system. As bacteria consume oxygen in the sample, the pressure in the bottle headspace drops.

BOD tester is widely used in municipal wastewater, industrial wastewater, environmental monitoring, university research, domestic wastewater, agriculture and other fields.
