From Tracer Products, the TP-9360 Pro-Alert is a portable refrigerant leak detector that features high-performance heated-diode sensor technology to accurately detect refrigerant leaks down to 0.03 oz/per year. It 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’s self-calibrating to neutralize background contamination, sensitive to both R-12 and R-134a refrigerants, and certified to meet SAE J1627 standards.

The cordless, compact PRO-Alert is specifically designed to make leak detection efficient and easy. Users simply turn it on and it’s ready for inspection instantly. Its 17 in (43 cm) long, chrome-plated, flexible metal probe easily gets into tight spots, Tracer says, and holds its position for more thorough inspection. It includes a built-in positive displacement pump that draws a test sample into the detector for fast, accurate sensing.

It’s powered by two D-cell alkaline batteries (included), and comes packed in a rugged plastic carrying case.
