Patent ID: 7022993

Claim:
A portable handheld infrared (IR) leak detector for refrigerant gas leaks, comprising in combination: a probe for being placed approximately 0.635 centimeters (approximately ¼ of an inch) adjacent to a suspected refrigerant gas leak sample that is suspected to being emitted from a single refrigerant pressurized gas leak source; an infrared (IR) chamber attached to the probe; an air pump adjacent to the IR chamber having a continuous sampling rate of at least approximately 100 cc/min, the air pump for drawing the refrigerant gas leak sample into the IR chamber; a sensor adjacent to the IR chamber for detecting whether the suspected gas leak sample is being emitted from the single refrigerant gas leak source; and a handheld housing for supporting the probe, the chamber, the air pump and the sensor so that the leak detector is portable and carryable in a single hand, wherein the leak detector detects a leak in the single refrigerant pressurized gas leak source without introducing or mixing a secondary tracer within the leak detector.
