The SV-Multigas-2 is a dual oxygen (O2) and carbon dioxide (CO2) monitor designed for vehicles operating in the upper atmosphere. Housed in a robust, compact enclosure, the unit is ideal for use in airborne delivery systems, satellites and aircraft cabins. Since 2014 the SV-Multigas-2 has been successfully used in rockets travelling to outer space.

Flexibility

The SV-Multigas-2 incorporates user maintainable analogue sensors that provide a 1 to 5 V output. This modular approach to gas monitoring ensures that our customers have the flexibility to integrate the unit into their own system. It can be either installed directly in the gas path or used for general air monitoring.
