Tracer Products has introduced the TP-9360 PRO-Alert, a portable refrigerant leak detector that features high-performance heated-diode sensor technology to accurately detect refrigerant leaks down to 0.25 oz per year (seven g/year). 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 help pinpoint leaks fast. The cordless, compact PRO-Alert is specifically designed to make leak detection efficient and easy. Simply turn it on and it’s ready for inspection — instantly. Its 17 in (43 cm) long, chrome-plated, flexible metal probe easily slithers into tight spots and holds its position for more thorough inspection. 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 (included), conveniently packed in a rugged plastic carrying case.
