The Tracerline TP-9364 PRO-Alert 2791 comes equipped with a three-position sensitivity switch, to help prevent false triggering and to provide for easier diagnosis.
The SAE J2791-certified detector is sensitive to R-12, R-134a and all other HFC refrigerants. With a sensor life of 1,000 hours or more, the infrared sensor is resistant to contamination by exposure to refrigerant. The unit includes a high-efficiency air sampling pump and a rubber-coated, flexible metal probe that fits into tight places. It also features an audible alarm and multiple LEDs to communicate when a leak is detected.
The unit is run by a rechargeable NiMH battery, which last more than six hours between charges. It also comes with a charging status indicator that alerts the user to low battery or infrared sensor failure.
