Chelsea Technologies has upgraded its Sea Sentry washwater monitoring system
The Sea Sentry system provides users with a full-range PAH measurement using a proven and highly accurate sensing technique and has been certified by DNV GL and ClassNK. Chelsea Technologies said the system has now been optimised for scrubber-equipped vessels.
Key changes will include an upgraded PAH+ sensor. In line with IMO regulations owners are required to perform polycyclic aromatic hydrocarbon (PAH) testing, pH, turbidity and temperature testing.
The company said it has developed a new standard to enable crews to quickly and easily check the calibration status of the turbidity and PAH+ sensors. These solid reference standards are designed to save time and money for the customer and extend the calibration interval out to 2 years. Users can check the calibration on board, with step-by-step instructions on their use integrated into the software to monitor washwater.
The connector style used on the turbidity and PAH+ sensors has been changed to a binder connector. The same connector has been added to the pump allowing pumps to be swapped in and out more easily if required. Some alterations have been made to the cabinet enclosure to increase ingress protection beyond the existing IP65 rating and external labels on the cabinet have been rearranged to make them more user-friendly and easier to understand.
The top electronics enclosure has been upgraded to improve the colour coding of the fuse holders and upgrade the display. Chelsea Technologies said this will make the wiring less complicated and easier to manage.
