Real-Time Sulfur Measurement for Diesel Aftertreatment Testing
Why the Sulfalyzer?
Meeting EPA requirements for Diesel Aftertreatment Accelerated Aging Cycle (DAAAC) testing demands precise sulfur control in fuels. The Sulfalyzer provides real-time sulfur measurement with accuracy within ±1 ppm, eliminating the delays, risks, and costs of traditional methods.
Cost-effective ROI – Faster return on investment compared to x-ray based systems.
6-second update rate – Enables real-time monitoring and control of the fuel blending process.
EPA-aligned accuracy – Designed to meet regulatory sulfur measurement standards.
Supports safer testing – Avoids the health and safety hazards associated with x-ray spectroscopy and SO₂ injection methods.
