From the Manufacturer
CPS Products Electronic Refrigerant Leak Detector is designed to ensure efficient leak detection. It features a patented Ion-Pump sensor with built-in selective filter housing and includes a high intensity bar graph display.
CSLS790B Features: -Patented Ion-Pump sensor with built-in selective filter housing.-0.25oz/yr (7g/yr) leak rate of HFC..-10 high intensity bar graph display.-R12 and R134a Deluxe Leak SeekerÂ® Detector. Options: -Over 100 computer generated tones varying in intensity with leak size. Specifications: -Lock-out modeThe LS790B Leak-Seeker® combines the most advanced microcomputer circuitry with field proven Ion-pump sensor technology creating a highly sensitive, accurate electronic refrigerant leak detector. Over 100 computer generated tones and a high intensity bar graph display quickly alerts the user to carying halogen concentrations. Patented automatic calibration design eliminates the need for manual balance or tick rate adjustments while the user selectable 10 sensitivity ranges enables the LS790B to detect all refrigerants. Lock out mode is a unique feature that enables quick and easy locating of refrigerant leaks in highly contaminated search zones. In this mode, the unit will automatically and systematically store the recorded concentration levels of background refrigerant while initiating leak search, alarming only in the area of highest recorded concentration level, the actual leak source. Operating temp: 0 to 140F / -18 to 60C. 40 hours battery life using 4 "AA" alkaline batteries. Auto OFF after 15 minutes of inactivity. . Warranty: -2 yr warranty on material and workmanship.
