Dual Combustion Furnace Infrared Carbon and Sulfur Analyzer

QCS-3000G Dual Combustion Furnace Infrared Carbon and Sulfur Analyzer is a high-end combined infrared carbon and  sulfur analyzer of world-leading technology. Due to the diversity of specimens of users and analytical methods, the instrument is equipped with two sets of sample pretreatment units, i.e. high frequency induction furnace and tubular resistance furnace. The resistance furnace and the high frequency induction furnace share the same infrared detection system for the detection of content of output gases to be detected. It is easy to switch between the two furnaces. QCS-3000G Dual Combustion Furnace Infrared Carbon and Sulfur Analyzer can be used for the detection of carbon and sulfur in a wide range of specimens, such as steel, cast iron, alloy, metal ore, ceramics, cement, lime, rubber, coal, coke, refractory, carbide, graphite, oil, catalyst, soil and other solid materials.
