LEAK-SEEKER® Refrigerant Leak Detector

General Details

Refrigerant Leak Detector LS780C has a rugged, a three-position slide switch used to turn the instrument on & select either LO or HI sensitivity ranges. Visual indication of the leak size is provided by a high intensity LED varying in brightness with the concentration of the refrigerant.

Combines microcomputer circuitry with field-proven Ion-Pump® sensor technology creating a highly sensitive and accurate electronic refrigerant leak detector. 128 computer-generated tones and display alerts the user to varying halogen concentrations. Leak-Seekers are designed and manufactured in USA with U.S. and globally sourced components.
