CW-800

Equipment Description

The determination of water and released carbon dioxide is a special type of analysis that finds application, for example, in the quality control area of the cement and plaster industries. ELTRA's CW-800 has been conceived for the simultaneous and precise determination of CO 2 and H2 O , especially in limestone, gypsum and cement, as well as other types of samples such as ores, soils and minerals. This analyzer measures concentrations from ppm to 100% (depending on the weight of the sample).

The CW-800 is equipped with a resistance furnace with a quartz tube where the sample is oxidized at a temperature of up to 1000 ° C. The temperature can be precisely programmed in steps of 1 ° C and remains constant throughout the analysis cycle. Nitrogen is used as carrier gas.

The CW-800's detection system is highly sensitive, accurate, reliable, long-life, and can be tailored to individual user needs. This analyzer can be equipped with two independent infrared cells to ensure even more accurate measurement of CO
2 and H 2 O.
