| Applications | |
|
- In-situ hydrocarbon detection / monitoring - Water mass indicator studies (Gelbstoff) - Pipeline leak detection - Pollution monitoring - For use on profiling, towed, moored or ROV deployments - Biogeochemical oceanography
- Robust miniature PMT - High sensitivity - Built In Test (BITE) circuitry - Low power consumption - Analogue output - Optional temperature probe - Optional ambient light baffling cowl |
The UV AQUAtracka is a submersible fluorimeter to monitor the concentration of hydrocarbons (360nm) or Gelbstoff (440nm) in a wide range of oceanographic applications. In support of this, it has been designed to be deployed from undulating vehicles, moored or profiling systems. This robust, compact, lightweight instrument has built in test (BITE) circuitry which ensures high stability. The instrument is easy to use and gives accurate and repeatable measurements. The UV AQUAtracka's pressure housing is manufactured in titanium for long life. It utilizes a pulsed xenon light source, a miniature PMT as the detector and incorporates a 20-bit ADC under the control of a micro controller. Data output is factory set as logarithmic analogue. The turret mechanical arrangement and main PCB allows for an optional Pt100 temperature probe. This option allows user correction of the fluorescence signal quantum yield variation with temperature. For deck and laboratory applications a flow through cowling is available. The instrument is rated to 600m (6,000m option) and has an optional ambient light baffling cowl for use in surface waters. |
