Applications
The durable, low-maintenance Memosens CFS51 fluorescence sensor detects polycyclic aromatic hydrocarbons (PAHs) in compliance with MEPC.259(68) and MEPC.340(77). Its integrated solid-state reference enables onboard recalibration and adjustment via intuitive transmitter menu guidance, ensuring straightforward, foolproof calibration. This feature extends the factory maintenance interval to an exceptional 4 years.
The Memosens CFS51 delivers precise PAH measurements for inlet and outlet streams in marine exhaust gas scrubbers, accommodating all discharge water flow rates.
Certified by leading classification societies:
-
DNV (Det Norske Veritas)
-
LR (Lloyd’s Register)
-
BV (Bureau Veritas)
-
ABS (American Bureau of Shipping)
For EGCS washwater monitoring, the PAH sensor is offered as an approved complete solution with integrated pH and turbidity measurement.
