Description
Chelsea Technologies® UviLux PAH+ Sensor UV Fluorometer (PetroChek)
Sensor designed to help users understand the natural environment, improve water treatment processes, comply with ballast water and exhaust gas wash water monitoring regulations, monitor for pollution and contaminants in rivers and lakes, and support oceanographic research.
Features:
- Full PAH Range – Full 0 – 4,500 μg/L PAH phe eq measurement which provides full compatibility with all scrubber system flow rates
- Two year calibration intervals – allowing for uninterrupted monitoring
- Easy to use onboard sensor check – solid standards kit allows you to verify the sensor calibration onsite with easy to operate, robust and stable solid standards as part of the commissioning process, without the need for liquids or chemicals
- Compliant with current and upcoming IMO regulations
- Temperature compensated, referenced output
- High ambient light and turbidity rejection
- Robust and easy to clean
