Model ELD-1000 Pro-Alert uses heated-diode sensor technology to detect refrigerant leaks as small as 0.03 to 0.06 oz/year. The portable refrigerant leak detector has dual-sensitivity controls: a high-sensitivity setting when initially checking the general leak area and a low-sensitivity setting to home in on the exact leak site. It is self-calibrating to neutralize background contamination; is sensitive to CFC, HCFC and HFC refrigerants; and eliminates the need to reset or switch for different refrigerants.
