CT3400 Extractive Gas Analyser

CT3400 Extractive Gas Analyser

Cascade’s CT3400 system is designed for the continuous and real time monitoring of multiple gases in industrial processes or laboratories, including engine emissions monitoring, combustion and incineration analysis, among others. Configured as an extractive system, the CT3400 will continuously draw gas through the measurement cell, providing more accurate and sensitive measurements of the gas composition.
