The 682T-HP is designed for the on-line analysis of sulfur in highly viscous hydrocarbons such as crude and residual oil using XRT (X-ray Transmission) technology. This system is ideal for high temperature and pressure sample streams. With its rugged, time-proven proportional counter detector and X-ray tube source, the 682T-HP gives superb analytical precision with a sulfur limit of detection of 200 ppm. The 682T-HP key features include a fully integrated densitometer, automatic density compensation, touch-screen controls, password protected and rapid update rates.
