LECO 2-MINUTE SULFUR DETERMINATOR FOR COAL AND COKE Determine % sulfur in your coal or coke rapidly and accurately with the LECO* IR-33 sulfur determinator. Shorter analysis time lets you run three times the number of tests, compared to the conventional combustion titration system. And there are no chemicals to prepare. Instead, samples weighing up to 0.5 grams are combusted in a LECO induction furnace and measured by a Luft-type infrared detector. A heated delivery system gives higher recovery for more accuracy. Digital display reads directly in percent of sulfur. BCD output is available in 8421 logic for computer compatibility. In addition to its timesaving features, the IR-33 is simple to operate and completely solid-state for dependability and ease of service. Contact LECO today.
