UviLux Fluorometer for real-time monitoring of refined & crude hydrocarbons, CDOM, Tryptophan & Optical Brighteners
The UviLux is a family of sensitive, low cost, digital in-situ UV fluorometers designed for real-time monitoring of concentrations of refined & crude hydrocarbons, Coloured Dissolved Organic Matter (CDOM) and Tryptophan, a surrogate marker for Biological Oxygen Demand (BOD), optical brighteners and bacterial contamination in waste, recycled and natural water supplies.

The UviLux is an innovative, sensitive, low cost, in-situ digital UV fluorometer providing many unique features. Variants of the UviLux enable real-time monitoring of the following parameters: Polycyclic Aromatic Hydrocarbon (PAH); Coloured Dissolved Organic Matter (CDOM); Tryptophan-like fluorescence, which is a surrogate marker for Biological Oxygen Demand (BOD) and is associated with bacterial contamination in waste, recycled and natural water supplies; and Optical Brighteners used for detecting household wastewater misconnections.
The UviLux uses a deep UV LED light source and a miniature Photomultiplier detector to provide state-of-the-art measurement sensitivity at the parts-per-trillion level. Fluorometer sensitivity and hence measurement dynamic range is fully user configurable for different applications. Sophisticated electronic signal processing, combined with cowl design principles employed in our UV AquaTracka, enables the UviLux to operate successfully in high levels of ambient light. The high quality optical filtration used in both the excitation and emission optical paths gives excellent turbidity rejection, while internal referencing of the LED light source intensity provides long-term calibration stability.
The UviLux can be deployed in a wide range of coastal, oceanographic and fresh water applications. The UviLux has a chemically inert acetal resin housing suitable for deploying independently as well as from submersible vehicles, moored or profiling systems. This robust, compact, lightweight fluorometer has low power consumption, is easy to use and gives accurate and repeatable measurements.
Two signals are obtained from the standard UviLux: a digital RS232 serial output in engineering units and a calibrated analogue voltage between 0.5V to 5V. Single RS422, SDI‑12 and 4-20mA outputs are also available as options. This flexibility makes the UviLux ideally suited for integrating into many different systems and platforms.
The Windows based Tplot software supplied with the fluorometer allows the user to both plot and record time stamped data when operating the UviLux directly from a PC and gives control over many instrument parameters, including: sampling rate, detector sensitivity and calibration factors. Although small and low cost, the UviLux maintains the performance standards and build quality associated with CTG’s range of in-situ fluorometers.

The standard UviLux fluorometer is supplied with transit case, handbook and Windows based Tplot software. There is now a range of accessories available to compliment the UviLux (see below). You will need to decide on cable type, length and cable termination. You will also need to give consideration to how you wish to interface the fluorometer to either a laptop, PDA or your own system.
