Tracer Products' TP-9360 PRO-Alert is a portable refrigerant leak detector that has high-performance heated-diode sensor technology to accurately detect refrigerant leaks down to 0.25 oz per year (7 g/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 is self-calibrating to neutralize background contamination, sensitive to both R-12 and R-134a refrigerants and certified to meet SAE J1627. Its 17-inch long, chrome-plated, flexible metal probe easily slithers into tight spots and holds its position for more thorough inspection.
