Tracer says the leak detector uses a state-of-the-art infrared sensor to accurately detect refrigerant leaks down to 0.1oz/year (3 g/year). A three-position sensitivity switch minimizes false triggering and allows for easy diagnosis of small, medium and large leaks, the company says. The unit is sensitive to R-12, R-134a, R-1234yf and all other HFC refrigerants, and Tracer says it is certified to meet the new SAE J2791 standard for electronic refrigerant detectors.
The PRO-Alert 2791 is powered by a rechargeable NiMH battery, which provides more than six hours of use between charges. Tracer says on-board diagnostics indicate charging status, and alert the user to low battery or infrared sensor failure. The unit also can be used with an AC power adapter and a 12 VDC power adapter with cigarette lighter plug (included), the company says.
