High-specification digital continuous emissions (CEMS) analyzer, designed for multi-gas measurement of criterion pollutants, greenhouse gases and reference oxygen. The advanced SERVOPRO 4900 Multigas delivers high-performance multi-gas monitoring designed specifically for the continuous emissions monitoring of flue gas.

This sensitive analyzer uses a combination of Servomex’s leading-edge, patented, digital sensing technologies, including Paramagnetic O2, and the non-dispersive infrared (NDIR) techniques of Single Beam Single Wavelength (SBSW) and Gas Filter Correlation (GFx).

When combined with a suitable sampling system the 4900 Multigas provides unparalleled MCERT/QAL1 measurements of criterion pollutants NO, SO2 and CO, plus O2 and greenhouse gases CO2, N2O and CH4.

The 4900 Multigas delivers this impressive monitoring power with a low cost of ownership, for a highly attractive analytical package.

Designed to be compact and robust, the 4900 Multigas requires minimal cabinet space and can be easily integrated into other systems, helping to reduce installation costs. 

With low operational requirements, facilitated through long calibration intervals by ultra-stable, high performance sensing technologies and auto-calibration capabilities, the 4900 Multigas is an ideal, affordable CEMS solution.

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.
