The Compass Refrigerant Leak Detector features a patented heated diode sensor, specifically designed for residential and commercial Air Conditioning leak detection application.

The Compass provides the optimal balance of features, function and value. This easy-to-use hand-held refrigerant leak detector delivers excellent sensitivity to all refrigerants, up to 0.15 oz/year.

Unlike some other leak detectors available on the market, this clever unit can pinpoint the leak source quickly through the high/low sensitivity adjustment; LED’s illuminate progressively to convey leak size and a water-resistant filter protects the sensor from job site contaminants such as dust, dirt and oil.
