How NDIR Gas Detection Works

Based on the image showing the NDIR (Non-Dispersive Infrared) gas detection method, here's a simple explanation of how it works:

  1. IR Source: The orange circle on the left emits infrared light (similar to heat waves).
  2. Gas Sample Chamber: The light travels through this blue chamber containing the gas sample being analyzed.
  3. Filters and Detectors: The light then passes through two different paths:
  4. Detection Process:
  • If the target gas is present in the chamber, it will absorb some of the infrared light passing through the active path
  • By comparing the readings from both detectors, the system can determine if the target gas is present and in what concentration
  • The more gas present, the more light is absorbed, and the greater the difference between the two detector readings
