BOD-Wader and BOD-Wader Pro systems from Chelsea Technologies Group allows water process engineers to assess real-time, in situ levels of BOD in water systems. This is achieved by detecting UV Tryptophan fluorescence, which recent publications have shown correlates with the standard 5-day Biological Oxygen Demand (BOD ) test.
The BOD-Wader comprises a CTG UviLux fluorometer and a Hawk handheld display and logging unit. CTG’s UviLux fluorometers detect UV fluorescence with industry-leading sensitivity and selectivity and have been optimised for minimal interference from water turbidity.
Data is displayed on the Hawk’s colour touchscreen and logged internally. If required, the Hawk can be programmed to apply a user calibration to the reported BOD values. The Hawk also incorporates a GPS receiver so that all logged data can be position and time stamped.
