Signal Group’s involvement in engine emissions testing dates back to the very beginning of the company in 1977. Since that time, a commitment to research and development has assured the provision of analysers featuring the latest advances in technology, designed to test to the latest Standards.
The new S4 analysers are particularly well suited to engine testing. The instrument screen has been replaced by a detachable tablet so that the operator can control the analyser via Bluetooth from outside of the test cell. In addition, the analysers have Ethernet capability so that users can connect with their instruments from anywhere and at any time.
In contrast with many competitive systems, the Signal analysers are able, if necessary, to operate completely independently, which is a major advantage during service operations and when an analyser is off-line for any reason.
Each analyser is designed to meet the latest USEPA 1065 and EURO 6 requirements.
Flame Ionisation Detector (FID) analysers for gas purity, air separation plant, engine emissions, combustion studies and process plant VOC abatement monitoring.
Chemiluminescent Detector (CLD) for NOx measurement in engine emissions, combustion studies, process plant, CEMS and medical gas production.
NDIR Multi-gas analyser series for industrial gas applications, combustion research, emissions monitoring and gas purity measurement (with optional oxygen analyser).
Dual FID, dual CLD and CO hi, CO low, CO2, CO2 EGR and O2 are offered as standalone analysers built in 3-unit 19” enclosures.
Signal Group also produces a wide range of sample handing modules such as heated prefilter units, multichannel sample selectors and flexible heated lines. In combination with the Signal Group 401 system controller, the company is able to build a complete emissions analyser system with automation/logging for most applications.

Setting the Standard in Gas Analysis: Why Reference Methods Matter In the rigorous domains of emissions monitoring, industrial process control, and advanced atmospheric research, the precision and reliability of gas analysis instrumentation are not merely advantageous; they are foundational to regulatory compliance, environmental stewardship, and scientific advancement. The designation of
Understanding the Role of Continuous Emissions Monitoring Systems (CEMS) In an increasingly regulated world, the ability to accurately monitor emissions in real time is no longer a luxury—it’s a necessity. Continuous Emissions Monitoring Systems (CEMS) provide the vital data industries need to: From power generation to cement production, from waste
The Flame Ionisation Detection (FID) method was first developed in the 1950s for the laboratory analysis of organic chemicals. Later, when environmental regulations began to limit the emissions of volatile organic chemicals (VOCs) in the 1970’s and 1980’s, the FID method was adapted for emissions monitoring. Signal Group was one
