EmailThe EM-5 infrared module is a gas analysis module based on Non-Dispersive Infrared (NDIR) absorption spectroscopy. Comprising a light source module, gas chamber, detector module, and control unit, it enables precise quantitative analysis of multiple gas components including CO₂, CO, CH₄, N₂O, SF₆, HC, and H₂O.
High circuit stability with low temperature drift and low detection limit
Reference methodology eliminates long-term light source attenuation
Short response time (as fast as 3 seconds)
Integrated temperature/pressure compensation ensures high measurement accuracy
Wide flow rate range (0.5L–2L/min) with customizable client configurations
Modular design for easy maintenance and seamless integration
Pulse-modulated light source delivers extended lifespan and cost-effectiveness
Specialized chamber wall treatment maximizes optical signal utilization for demanding applications
Customizable measurement ranges from μmol/mol to percent levels per client requirements
