EZ-MAT: Eltra Carbon / Sulfur Analyzer CS-800


The ELTRA CS-800 with induction furnace is ideally suited for the simultaneous determination of carbon and sulfur in inorganic samples. It provides quick and precise analysis results and can be used for a variety of applications.
The carbon / sulfur analyzer CS-800 is equipped with up to four independent infrared (IR) cells which allow for precise simultaneous analysis of high and low carbon and sulfur concentrations in one measurement. The sensitivity of the cells can be customized individually by selecting the length of the IR path to ensure the optimum measuring properties for each application.

Application Examples

alloys, carbides, cast iron, cement, ceramics, copper, glass, iron, minerals, ores, refractory metals, sand, steel, titanium, waste
