The Memosens CFS51 fluorescence sensor accurately measures the PAH concentration in the inlet and outlet of marine gas scrubbers (ECGS) offering all benefits of the Memosens digital sensor technology.
The solid-state reference allows the ship's crew to calibrate and adjust the sensor directly on board, which helps extend the sensor's factory service interval to 4 years.
The sophisticated design of the assembly, as well as the angled installation position in which the assembly holds the sensor, prevents air bubbles from influencing the measured value.

The rugged and low-maintenance Memosens CFS51 fluorescence sensor measures polycyclic aromatic hydrocarbons (PAHs) in accordance with MEPC.259(68) and MEPC.340(77). Thanks to the practical solid-state reference, you can readjust and calibrate the sensor onboard the vessel - supported by user-friendly guidance in the transmitter menu. This makes the calibration procedure simple and error-free, and you benefit from an exceptionally long factory maintenance interval of 4 years.
Memosens CFS51 measures PAHs with high accuracy in both the inlet and outlet of marine exhaust gas cleaning systems (scrubbers) and is suitable for all discharge water flow rates.
The sensor is certified by the following approval bodies:
DNV (Det Norske Veritas)
LR (Lloyd’s Register)
BV (Bureau Veritas)
ABS (American Bureau of Shipping)
For washwater monitoring in EGCS, the PAH sensor is also available as an approved all-in-one solution including pH and turbidity measurement.
Benefits
The uniquely long factory maintenance interval saves you a lot of costs and organizational effort
The optionally available flow assembly holds the sensor at the ideal installation angle to minimize disturbing influences caused by air bubbles. In addition, it can be tilted for quick mounting and dismounting of the sensor.
DNV approved integrated turbidity correction in the range of 0-50 FNU
High material compliance of sensor and flow assembly according to IACS E10 (flame retardancy)
The solid-state reference makes calibration very easy for the end user - and you can completely eliminate the need for toxic phenantrene, which increases safety for your employees and the environment
The suitability of the solid-state reference for calibration and readjustment of the PAH sensor on board was confirmed by DNV
Measurement of hydrogen sulphide with the use of Tunable Diode Laser technology, eliminates issues of traditional methods giving quick analysis results and reducing cost of ownership.
