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.
For industries and processes including power generation, petrochemical, refining, waste incineration, iron and steel, pulp and paper, and cement manufacture, continuous emissions monitoring is a regulatory requirement.
The solution must be capable of offering the highest sensitivity and accuracy when dealing with multiple measurements for pollutants and greenhouse gases. No matter what your application needs, you’ll want a solution that’s easy to install and operate, while delivering attractive affordability. And we don’t believe you should have to compromise.
The 4900 Multigas meets all your CEMS requirements through a specific design and feature set optimized to continuous flue gas emissions monitoring applications. This compact, small-footprint analyzer integrates effortlessly into your established systems and, when used with the correct sampling system, delivers high grade multi-gas monitoring of criterion pollutant and greenhouse gases (% O2, CO2 and CO, plus ppm SO2, NO, CO, CH4, and N2O). The 4900 Multigas combines three sensitive and highly stable non-depleting technologies to deliver unsurpassed measurements you can rely on – Paramagnetic, Single Beam Single Wavelength NDIR and Gas Filter Correlation NDIR. In addition to its performance, the 4900 Multigas also comes with analog/serial outputs, with digital communications protocols Serial Modbus, PROFIBUS, and Ethernet (Modbus TCP/IP) for added flexibility in configuration and set-up. An external NOx converter can be used to analyze and speciate NOx, NO and NO2.
Added to its considerable measurement performance and stability, the 4900 Multigas delivers highly attractive cost reductions over product life. Not only is this device optimized for easy set-up and flexible integration, but an auto-calibration function permits easy, low-cost remote calibration. The 4900 Multigas allows diagnostic values to be exported for early detection of problems for preventative, or even predictive maintenance.
If you’re putting together a system for continuous emissions monitoring, our team can provide the added expertise you need. Get in touch today for optimum project performance.
