Engineering quality gas analysis systems for critical applications worldwide.
For nearly five decades, Signal Group has designed and manufactured high-performance gas analysers for applications where accuracy, stability, and long-term reliability matter most.
We do not simply build instruments.
We engineer measurement systems that protect compliance, safeguard operations, and deliver data customers can trust.
Signal Group is uncompromising in its approach to measurement quality. We prioritise accuracy, long-term stability, and robustness in real-world operating environments over headline specifications. Every design decision is guided by engineering judgement, ensuring reliable, trustworthy data that protects customers from downtime, non-compliance, and avoidable risk.
Signal analysers are built to last. Manufactured in the UK and engineered for long service life, our instruments are routinely supported and operated for well over a decade. We reject planned obsolescence in favour of serviceable designs, long-term spares availability, and strong lifecycle value for customers.
Signal combines proven technologies with decades of application experience to address customer requirements effectively. We listen carefully to customer needs and constraints, then apply our established designs, engineering platforms, and expertise to deliver solutions that are practical, reliable, and supportable - adapting where appropriate, without compromising robustness or long-term performance.
Accurate gas analysis depends on more than the analyser alone. Signal takes responsibility for the complete measurement chain, including sample extraction, conditioning, calibration, and system integration. By delivering complete solutions, we ensure measurement integrity, consistency, and confidence in the data our customers rely on.
Signal provides fast, effective support through direct access to knowledgeable engineers who understand both the technology and the customer’s operating environment. We respond quickly to technical queries, service needs, and operational issues, helping customers resolve problems promptly and minimise downtime. From commissioning through to servicing, spares, and consumables, we aim to build long-term relationships by combining speed, continuity, and technical expertise.
Manufactured in the United Kingdom, Signal Group combines British engineering expertise with a trusted global distribution network. From Europe and North America to Asia-Pacific, the Middle East, Africa, and South America, our experienced partners provide local sales, technical support, and service continuity. This ensures customers benefit from direct engineering accountability at source, alongside responsive, region-specific expertise wherever they operate.
