Designed specifically for the maritime industry, this fuel sampling device ensures accurate fuel analysis during vessel refueling. It collects a 5L composite sample in full compliance with MARPOL Annex VI regulations. The sample is then sent to a laboratory to assess the quality and purity of the supplied fuel. Over the past 40 years, Marco Marine A/S has continuously developed and refined this device to deliver reliable performance under demanding conditions and with modern fuel types.

At Marco Marine A/S, we ensure our customers' engines perform at their best, wherever their vessels operate.

We look forward, to continue servicing existing and new customers worldwide.
