HORIBA SLFA-20

The SLFA-20 is designed specifically to meet the recent demanding needs of measuring the new low sulfur fuels, diesel and RFG. The sensitivity and low-level detection has been improved while maintaining all the previous high-performance characteristics of HORIBA’s SLFA series. Using the X-ray fluorescence technique, fast and accurate measurements can be carried out in compliance with the ASTM D4294 method, either in the lab or in the field.

This compact analyzer has a range of 0 to 4 wt% of total sulfur, with a lower detection limit of 20ppm and repeatability of 15ppm. Accuracy is ensured by storing up to five calibration curves and an alphanumeric keyboard input aides in identifying samples.
