The instrument is specially designed to determine sulfur content in the petroleum products. Adopts energy-dispersive principle, and with electrical, mechanical and microprocessor integration design, so it is rapid and accurate. It can meet the requirements of National Standard GB/T 17040 and GB/T11140 on repeatability and reproducibility, and it can also meet requirements of ASTM D4294-03 on these indexes. It provides a measure to determine sulfur content during petroleum or petrochemical production process.
