The innovative UniLux range of digital in-situ fluorimeters provides the user with increased functionality when compared to other fluorimeters currently available on the market. CTG has used expertise gained within its Life Science Group that have resulted in a significant reduction in production costs, providing the marine, fresh water, surveying and process control markets with a low cost, high performance sensor. Users can select from a wide range of fluorescent parameters, specifying the UniLux tailored to their specific monitoring requirements.
Two signals can be obtained from the standard UniLux: the first is a digital RS232 output in engineering units, the second a 0V to 5V volt calibrated analogue output derived from the digital signal. A single RS422 output is also available as an option. This flexibility makes the UniLux suitable for integrating into many different systems and platforms.
A Windows based Graphical User Interface (GUI) is provided that allows the user to both plot and record time stamped data when operating the UniLux directly from a PC and gives control over many instrument parameters, including: sampling rate, calibration factors and dynamic range.
The dynamic range of the UniLux can be adjusted simply by varying the LED intensity using the GUI, while still maintaining the factory set calibration via the internal referencing of LED output.
Although small and low cost, the UniLux fluorimeter maintains the performance standards and build quality previously seen in the CTG’s range of in-situ fluorimeters.
