CO2/CH4 Sensor

A CO2/CH4 sensor is a dual-analyte gas detection instrument measuring carbon dioxide and methane concentrations through non-dispersive infrared (NDIR) spectroscopy or catalytic bead technology, enabling environmental monitoring, industrial safety assessment, and atmospheric research applications. The dual-sensor approach provides comprehensive carbonaceous gas characterisation within portable single-unit configuration.

Premium CO2/CH4 sensors employ NDIR sensing for CO2 measurement across 0–10,000 ppm range detecting infrared absorption at characteristic 4.26 micrometres (CO2) and 3.31 micrometres (CH4) wavelengths. Measurement accuracy typically achieves ±3% or ±50 ppm whichever is greater, sufficient for environmental and occupational safety applications. Response time on NDIR sensors spans 2–10 seconds enabling real-time monitoring of dynamic gas concentration variations.

Environmental applications include indoor air quality assessment identifying inadequate HVAC performance, underground confined space screening identifying hazardous gas accumulation before personnel entry, and agricultural monitoring quantifying methane emissions from livestock operations. Landfill and wastewater treatment facility monitoring tracks biogas composition optimising energy recovery and emission control.

Data logging with timestamp capability enables trend analysis across extended monitoring periods, with configurable alarm thresholds triggering when concentrations exceed safe limits. Portable battery-powered variants with 8–12 hour endurance enable extended field deployment without external power requirements.

In Pakistan, CO2/CH4 sensors support environmental protection authority monitoring and industrial facility safety assessment.
