LeakHawk Pro™refrigerant leak detector
How the LeakHawk Pro is built
Infrared sensor
The sensor detects refrigerant by optical measurement rather than a heated tip. That means the detection method does not rely on a chemical reaction at the probe, which is how many older detectors work.
Refrigerant types
The detector is listed for R22, R32, R1234yf and major A2L blends, along with R11, R134a, R404a and R417A. It also covers CFC, HCFC and HFC families, so one tool serves many systems.

Proximity alerts
As the probe moves closer to a leak, the beeper speeds up and the LCD display changes. You follow the alert pattern along a line or fitting until it reaches its strongest point.
Probe and controls
The 9.44-inch probe bends so you can position it behind coils and inside cramped bays. The controls are made for gloved hands, so you can keep gloves on while you scan.

LeakHawk Pro is a refrigerant leak detector for technicians and homeowners who need to locate where a cooling system is losing refrigerant. As an infrared refrigerant leak detector, its sensor works optically instead of relying on a heated diode tip.
The bendable 9.44-inch probe reaches behind coils and into tight bays, and the glove-friendly controls suit job-site work. An LCD and progressive beep alerts show how close the probe is to the source of a leak.
Used as an HVAC leak detector or an AC leak detector, the handheld unit identifies R22, R32, R1234yf, R134a, R404a and A2L blends. It is rechargeable and carried in a protective case.
