CT2100 - OnStack Multigas Analyser

The CT2100 analyser has been developed for harsh enviroments and continuous real time monitoring of N0, NO2, SO2, CO2 onboard ships.

Designed for installation at the measurement point (in a stack or duct) they are easily mounted on a stabbing and are configured to maintain a flow of gas at constant temperature and pressure within a sample cell, thereby avoiding condensation and allowing accurate and sensitive measurements of key greenhouse gases.


Gas DetectionRange Detection Limit
Nitric Oxide (NO) 0-2000ppm 20ppm
Nitrogen Dioxide (NO2) 0-300ppm 3ppm
Sulphur Dioxide (SO2) 0-1750ppm 17.5ppm
Carbon Dioxide (CO2) 0-10% 0.10%





* Measurement range can vary depending on the sample gas temperature.
