According to Tracer Products, TP-9364 uses 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 unit is sensitive to R-12, R-134a, R-1234yf and all other HFC refrigerants, and is certified to meet the new SAE J2791 standard for electronic refrigerant detectors, the company says.
Unlike heated sensors on competitors’ units, the PRO-Alert 2791’s infrared sensor offers consistent response throughout its life. In addition, it will not become contaminated by exposure to large amounts of refrigerant, the company says.
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 can also be used with an AC power adapter and a 12 VDC power adapter with cigarette lighter plug (included). All components are packed in a rugged plastic carrying case. The AC adapter is available in 120V, 230V, 240V and 100V versions.
