According to Tracer, the PRO-Alert features dual-sensitivity controls — a high-sensitivity setting when initially checking the general leak area, and a low-sensitivity setting to hone in on the exact leak site. It is self-calibrating to neutralize background contamination, sensitive to both R-12 and R-134a refrigerants, and certified to meet SAE J1627. Its variable-intensity audible alarm and flashing LED are said to help pinpoint leaks fast.
The cordless, compact PRO-Alert is specifically designed to make leak detection efficient and easy, Tracer says. Its 17 in. long, chrome-plated, flexible metal probe slides into tight spots and holds its position for more thorough inspection. Tracer also says it includes a powerful, built-in positive displacement pump that draws a test sample into the detector for fast, accurate sensing.
The PRO-Alert comes complete with sensor, replacement filters and two D-cell alkaline batteries packed in a plastic carrying case.
