MINI^tracka II augments Chelsea's renowned range of AQUA^tracka submersible fluorimeters. The emphasis on the different variants of MINI^tracka II  is on low cost, size and power consumption - whilst still retaining excellent sensitivity, without sacrificing the all important turbidity rejection. All Chelsea's fluorimeters are notable for their ability to make measurements in high levels of daylight.

Specimen excitation is from a high brilliance blue LED combined with optical filtering. Optical emissions are detected by a large area, low temperature coefficient (tempco) photodiode which feeds a low noise preamp that, together with phase sensitive detection, gives an overall electronic noise figure close to the theoretical minimum possible. The performance of  MINI^tracka II has a high degree of insensitivity to water temperature changes due to the low tempco of the new generation SQW LEDs, the selected photodiode used and the careful circuit design.

The sophisticated design of the electronic signal processing, combined with cowl design principles of the UV AQUA^tracka incorporated in the pressure housing, enables it to operate successfully in high levels of ambient light. Hence, using  MINI^tracka II means there is generally no requirement to pump sea water through a dark observing chamber, thus obviating the need for water flow corrections - not to mention the cost, inconvenience and power drain of a pump. For deck & laboratory applications, a flow through manifold is available.

The ease of use and installation is further enhanced by the provision of galvanic isolation between the power 0 volt and signal 0 volt lines within MINI^tracka II, thereby interrupting possible 'ground loops'. The high efficiency, proprietary design DC converter can also handle the unusually wide range of supply voltages between 7V and 40V without significant change in a power drain of 0.7W. The output will drive almost any sort of measuring or data logging device. It should be noted that the output of MINI^tracka II is linearly related to concentration and not logarithmically as might be expected from its AQUA^tracka origins.

Flow Through Manifold is now available - this is designed to convert the MINt^tracka II from an in-situ fluorimeter to a flow through sensor for AquaLine Ferrybox and process control applications. Click for more information
