Product Description The Robinair No. 22791 uses infrared optics to create a refrigerant leak detector that combines sensitivity, speed, battery life, portability, and ease of use. This unit detects leaks as small as 0.15 oz/year, and meets SAE J1627, J2791, and J2913 standards. No. 22791 comes with a wall charger and a car charger for its compact lithium-ion battery—which can power the leak detector for up to eight hours of continuous operation before needing to recharge.

The PEAK LED illuminates when this function is turned on. Turning the PEAK function off clears the peak information.
service valves with caps in place, brazed or welded areas, and areas around attachment points and hold-downs on lines and components. If looking for an apparently larger leak, check first at the 7 g/yr or 14 g/yr position. C. Always follow the refrigerant system around in a continuous path so no areas of potential leaks are missed. If a leak is found, continue to test the remainder of the system. D. Recheck service valves with caps removed.
If the 22791 does false trigger on a chemical listed below, allow the leak detector to clear for a minimum time listed in the table.
