Photoacoustic IR (PIR) addresses the challenges linked with zero drift by obviating the necessity to compare outcomes with a reference sample. PIR systems directly gauge pressure alterations arising from the absorption of infrared light by the refrigerant within the sample.
The magnitude of pressure change correlates directly with the concentration of the gas. By eliminating the reliance on a reference gas for comparison, PIR effectively eliminates the potential for "zero drift." With Refrigerant Gas Monitoring Technology and Thermal Gas Systems utilizing Photoacoustic Infrared instruments, 'zero-is-zero' is upheld.
