Portable Infrared Gas Analyzer

Portable infrared gas analyzers detect and measure specific gas concentrations in ambient air or process samples. They work by measuring infrared light absorption at wavelengths matching the target gas molecule. These handheld or shoulder-carried instruments bring field-grade gas measurement to remote locations. Operators conduct leak surveys and environmental assessments without transporting samples to a fixed laboratory.

The detection principle uses a broadband infrared source directed through a sample cell. Optical filters select the specific absorption wavelength of the target gas. Carbon dioxide absorbs at 4.26 microns. Methane absorbs near 3.3 microns. Carbon monoxide absorbs at 4.67 microns. Additionally, dual-beam designs use a reference channel at a non-absorbing wavelength. This compensates for source intensity drift and optical contamination over extended field use. Measurement range covers 0 to 1000 ppm for trace gas work and 0 to 100% volume for high-concentration process gas applications.

Response time runs between 5 and 20 seconds for 90% of full reading. Furthermore, onboard data logging stores concentration readings with timestamps at intervals between 1 second and 1 minute. Memory retains between 10,000 and 100,000 data points before requiring export. USB or Bluetooth transfers stored data to analysis software. GPS-enabled models add coordinate data to each reading, producing georeferenced concentration maps from field survey walks.

Operating temperature range runs from -10°C to +45°C on field-grade units. Moreover, rechargeable lithium-ion battery packs provide between 6 and 12 hours per charge. This supports full-day field deployments without recharging stops. Housing uses impact-resistant ABS or polycarbonate with IP54 or IP65 protection ratings against dust and moisture ingress.

Tactical Supply Pakistan supplies portable infrared gas analyzers to industrial safety teams, environmental monitoring agencies, gas utility leak survey crews, and security screening units requiring accurate field gas measurement capability throughout Pakistan.
