SERVOPRO 4900 Multigas
The 4900 Multigas is a high-performance CEMS analyzer designed for a wide range of multi-gas measurements.
Specifically designed for Continuous Emissions Monitoring (CEMS) of flue gas, the SERVOPRO 4900 Multigas can deliver up to four simultaneous gas stream measurements. It combines Servomex’s leading-edge sensing technologies with a modern digital platform, for next-generation performance at a low cost of ownership.
The 4900 Multigas is backwards-compatible with existing 4900 installations and uses the same reliable measurement technology, providing trusted gas analysis combined with the advanced digital communications required by modern systems.
