The Robinair LD9-TGKIT Tracer Gas service kit gives technicians the tools necessary to use tracer gas in place of refrigerant to find A/C system leaks. The LD9TGKIT includes a hydrogen gas leak detector with sensor technology designed to detect a 5% hydrogen / 95% nitrogen tracer gas mixture. The detector's full color liquid crystal display (LCD) and sweep mode function convey messages, graphics, and prompts to help technicians locate the source of a leak and ensure that the leak detector is always at optimal performance. A patented 3 LED inspection light aids in locating and inspecting suspected leak sources.

Using tracer gas eliminates the need to use expensive refrigerant to find leaks. Filling a system with tracer gas is fast and effective, with a much lower cost than refrigerant.

Detects leaks as small as 0.5 ounces/year for R134a and .015 ounces/year for R1234yf.

The kit includes the LD9 tracer gas leak detector, 134a and 1234yf high and low side couplers, hose and regulator for tracer gas.
