Marine Fuel and Bunker Fuel Testing
The marine and shipping industry is facing stricter emission standards than ever before. To comply with IMO 2020, vessels must meet a 0.5% sulfur limit — a significant drop from the previous 3.5%. This means more frequent testing of marine fuels and, in some cases, investing in onboard testing equipment. EDXRF technology is a cost-effective solution that can help you stay compliant and avoid penalties.
We offer the affordable NEX QC, a compact benchtop EDXRF system ideal for spot-checking sulfur and ensuring quick compliance. We also offer NEX XT, an X-ray transmission process gauge, for continuous sulfur monitoring. This in-line system provides real-time measurement of sulfur for blending operations, bunkering terminals, and more.

Why choose EDXRF for marine fuel compliance testing?
Benchtop solutions for bunker fuel testing
NEX QC provides at-line sulfur analysis of bunker fuel onboard ships or at bunkering ports. It can also monitor nickel, vanadium, and iron content in bunker fuels or analyze fuels for zinc to check for lube oil contamination.
- Analyze sulfur (S) content in marine fuels down to low ppm levels
- Affordable option for testing onboard ships, ports, and labs
- Reduces the need to send samples to off-site labs
- Compact and rugged design that does not require an external computer
- Easy-to-use touchscreen interface and built-in printer
- Optional carrying case for portability
- Also offers compliance for ASTM D4294-21, ISO 20847, ISO 8754, IP 496, IP 336, and JIS K 2541-4.

On-line solutions for ship operators, blending operations, and more
For on-line analysis of bunker fuel testing and monitoring, NEX XT provides real-time measurement of sulfur. This system addresses the needs of refineries, pipelines, blending operations, bunkering terminals, and other storage facilities.
