Abstract
A gas detection and measurement system includes a light source, a light sensor, a test cell body having a first fluid port and a second fluid port, and first and second optical paths from the light source to the light sensor through the test cell. The first and second optical paths have different lengths. As fluid flows through the test cell body, light intensity measurements are taken along the first and second optical paths so that the concentration of a target gas within the fluid can be calculated.
