Servomex SERVOPRO 4900 Multigas Analyzer
Overview
The Servomex SERVOPRO 4900 Multigas is a high-performance continuous emissions monitoring system (CEMS) analyzer designed for a wide range of multi-gas flue gas measurements. Delivering up to four simultaneous gas stream measurements from a compact, small-footprint chassis, the SERVOPRO 4900 Multigas combines Servomex’s leading-edge, non-depleting sensing technologies with a modern digital platform to give plant operators next-generation performance at a low cost of ownership.
As the official authorized partner and exclusive regional representative for Servomex, Seven Star LLC proudly supplies the SERVOPRO 4900 Multigas to power generation, refining, and process facilities throughout the Sultanate of Oman and the wider GCC. Every analyzer shipped carries full manufacturer warranty and the regional technical support that regulatory-grade emissions monitoring demands.
Measurement Principle
The Servomex SERVOPRO 4900 Multigas combines three sensitive, highly stable non-depleting technologies to deliver measurements plant operators can rely on for regulatory compliance: Paramagnetic oxygen sensing, Single Beam Dual Wavelength (SBDW) non-dispersive infrared (NDIR), and Gas Filter Correlation (GFx) NDIR. Because these sensing technologies do not deplete or consume reagents over their operating life, the analyzer maintains long calibration intervals and stable accuracy without the frequent sensor replacement that affects electrochemical or depleting-cell alternatives.
This combination of technologies allows the SERVOPRO 4900 Multigas to simultaneously measure criterion pollutants and greenhouse gases from a single sample stream, oxygen, carbon dioxide, and carbon monoxide at percent level, alongside sulfur dioxide, nitric oxide, methane, and nitrous oxide at ppm level, giving plant operators a comprehensive emissions picture from one integrated instrument rather than multiple single-gas analyzers.
Engineering Design of the Servomex SERVOPRO 4900 Multigas
The SERVOPRO 4900 Multigas measures 132.5 mm (5.2 in) high in its standard chassis, or 265.5 mm (10.5 in) with the extended chassis, by 481.6 mm (19 in) wide and 544.2 mm (21.4 in) deep, weighing approximately 14 kg (30.9 lb) for the base unit. This compact, rack-mountable footprint integrates effortlessly into existing CEMS cabinets and control shelters, reducing installation costs compared to bulkier multi-analyzer configurations. An external NOx converter can be added to analyze and speciate NOx into NO and NO2 for facilities requiring full nitrogen oxide reporting.
The analyzer communicates via analog and serial outputs alongside digital protocols including RS232/RS485 Modbus, PROFIBUS, and Ethernet (Modbus TCP/IP) for flexible integration into plant SCADA and emissions reporting systems. An icon-driven color touchscreen provides intuitive local configuration and diagnostics, while a USB serial port supports data logging and software upgrades. Auto-calibration functionality enables low-cost remote calibration, and exportable diagnostic values support preventative and predictive maintenance programs.
Key Features
The Servomex SERVOPRO 4900 Multigas combines regulatory-grade accuracy with the low-maintenance operation that continuous emissions monitoring programs demand:
- Up to four simultaneous gas stream measurements from a single compact analyzer chassis.
- Non-depleting Paramagnetic, SBDW NDIR, and Gas Filter Correlation NDIR sensing technologies for ultra-stable accuracy.
- Measures O2, CO2, and CO at percent level plus SO2, NO, CH4, and N2O at ppm level.
- Certified to MCERTS EN 15267-1/2/3 and QAL1 EN 14181 for O2, SO2, CO, and NO.
- Auto-calibration function reduces ongoing operational costs and remote calibration effort.
- Digital communications via RS232/RS485 Modbus, PROFIBUS, and Ethernet Modbus TCP/IP.
- Backwards-compatible with existing 4900 installations using the same proven measurement technology.
- Compact, rack-mountable footprint simplifies integration into existing CEMS cabinets.
Industrial Applications
The Servomex SERVOPRO 4900 Multigas is specified across power generation, petrochemical, refining, waste incineration, iron and steel, pulp and paper, and cement manufacturing, wherever continuous emissions monitoring is a regulatory requirement. In Oman’s power generation and refining sector, the SERVOPRO 4900 Multigas’s MCERTS and QAL1 certification supports compliance reporting for criterion pollutants and greenhouse gas emissions from combustion and process sources.
As the officially authorized partner for Servomex, Seven Star LLC distributes the SERVOPRO 4900 Multigas to thermal power plants, petrochemical complexes, and industrial facilities across Muscat and the Sohar and Salalah economic zones. Its compact footprint and auto-calibration capability make it well suited for retrofit CEMS upgrades and new-build emissions monitoring systems throughout the GCC’s power and heavy industrial sectors.

Why Choose Seven Star LLC for Servomex Continuous Emissions Monitoring Systems
Specifying a CEMS analyzer correctly means confirming which certification standard (MCERTS, QAL1) your local regulator actually requires and designing a sample-conditioning system that matches your stack gas composition and moisture content — an analyzer that meets the letter of a datasheet but the wrong sampling design will fail commissioning audits. Seven Star LLC works with your environmental compliance team to confirm the correct SERVOPRO 4900 Multigas configuration and communication protocol for your plant’s reporting system before order confirmation, drawing on our authorized Servomex partnership across Oman and the wider GCC. We also support power generation and refining facilities in Sohar and Salalah with sampling system design guidance and coordinate calibration gas procurement so CEMS installations stay audit-ready from commissioning onward.
