Product offeringCore offering
Signal Group designs and manufactures high-performance gas analysers used for continuous emissions monitoring (CEM), process gas analysis, and environmental compliance. The product range covers multiple detection technologies—FID, CLD, NDIR, PMG and TDLS—spanning ultra-low ppb stack monitoring through to high-% process measurements, complemented by ancillaries for sample handling, gas conditioning, and test/calibration to deliver a complete measurement chain. The company sells and supports its products globally through a network of 41 distributors across 31 countries, backed by in-house service capabilities.
Product overview
Signal Group is a UK-based manufacturer of high-performance gas analysers for critical applications, operating since 1977. The product portfolio centers on the S4 Analyser Platform comprising rack-mounted and portable instruments utilizing five core detection technologies: Flame Ionisation Detection (FID) for VOC/THC measurement (S4 SOLAR, S4 SOLAR XPLORE, 3010 MINIFID, S4 SOLAR CEMNEX), Chemiluminescence (CLD) for NOx analysis (S4 QUASAR), Non-Dispersive Infrared (NDIR) for multi-gas measurement (S4 PULSAR, S4 GHG PULSAR), Tunable Diode Laser Spectroscopy (TDLS) for ammonia (S4 NEBULA), and Paramagnetic detection for oxygen (S4 AURORA). These are complemented by extensive ancillary equipment including sample handling systems (probes, heated lines, pumps, filters, coolers/dryers), calibration and test equipment (gas dividers, zero air generators, NOx converters, methane cutters), and custom turnkey system integration services. The S4 SOLAR CEMNEX represents the flagship integrated solution combining FID detection with heated sample handling and automated calibration in a single MCERTS-certified system.
