BACTI-Wader and BACTI-Wader Pro: Provides instant measurements of water-borne bacteria avoiding lengthy & potentially costly delays in obtaining labratory results

resizedBACTI Wader

Chelsea Technologies Group's BACTI-Wader and BACTI-Wader Pro systems allow surveyors and regulators to assess real-time, in situ levels of bacteria in water systems. This is achieved by detecting UV Tryptophan fluorescence, which has been shown to correlate with bacterial levels.

The BACTI-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.
