Portable leak detector with proven heated-diode sensor technology. The electrochemical heated-diode sensor resists dirt, water, oil, and other contaminants offering exceptional resistance to the effects of contamination.

• Equal sensitivity to CFCs, HCFCs, and HFCs eliminates resetting or switching for different refrigerants.
• Variable-intensity audible signal and single flashing LED to help pinpoint leaks.
• The automatic background compensation feature continuously monitors and automatically compensates for changing background "noise" without the need for manual adjustments by the operator.
